Our friend's girlfriend acts like my boyfriend and I don't exist

Hi all, this is a long and convoluted story, thanks for reading if you have the time, though the heading here gets the basic idea across. My question is if you think I should try to do anything here or just let it lie? Chapter 1: College, post-college, establishing relationships I'm a woman in my 30s but the story begins about 10 years ago when I was in college, where I knew two people, Lucy and Megan. Lucy and I were very close friends, but Megan and I were not. I interacted with Megan through things like club events or at parties, but that was the extent. Lucy and Megan were also friends with each other, but that was in a different social circle that I wasn't really involved in. I also always got the sense that Megan didn't like me. After college, we all move to different places and get jobs, start our post-college lives, but I remain friends with Lucy, and I know that Megan and Lucy stay in touch with each other. Somewhere around this post-college time, Megan meets someone named Matthew and they start dating. A few years pass, and all the people in this story including myself move to one City. I move into an apartment with Lucy, and Megan and Matthew move to the City and eventually move in together. Things are uneventful at this time, I get to know Megan a little better by way of Lucy but we're still not closer than acquaintances. Also at this time, Lucy becomes friends with Megan's boyfriend Matthew. Chapter 2: Things get messy COVID begins, and things start shifting around. Megan and Matthew move out of the City to be near family in another state. Lucy and I are doing our best in COVID times, we both are underemployed and in a scrappy survival mode together, though I'm observing that Lucy is really struggling with mental health and is depending on me a lot. But I'm still on her side and know we're in this together. We start spending time with a group of people who become our COVID pod, one of whom is a guy Patrick who I actually knew for many years prior but had never been very close to until this time. For later context, Patrick and Matthew had also been friends, and they stay in touch while Matthew is living out of state. Around this time, though, Lucy and I's friendship eventually gets strained beyond repair. Living together is definitely not helping, nor is post-COVID life where we still aren't really expanding our social circles or leaving the house as much as we used to. There were many other factors here that would take way too long to get into, but the result is: Lucy and I end our friendship. It was extremely messy, difficult, and painful as you can imagine. Lucy moves out of our apartment, at which point we are not speaking to eachother. This friendship ending in this terrible way puts me in a deep depression for many months. I re-started therapy around this time and saw that therapist for about the year following. A few months after this big friend breakup, I start dating Patrick. Patrick is in an odd in-between place, because he and Lucy were sort of "friends" prior to us dating, but he had also never had a great relationship with Lucy and in fact thought she kind of hated him. I explained what happened to Patrick, but in no way told him he couldn't be friends with Lucy. At this time, he doesn't make a conscious decision about what to do, he just lets it lie and sees if Lucy reaches out to him (she doesn't), but otherwise assumes if he ever runs into her somewhere he would say hi and see if she wants to talk about it. This doesn't happen. Quick recap: -Lucy and I no longer friends -Lucy and Megan still friends -Matthew and Patrick still friends -Megan is dating Matthew -I am dating Patrick Chapter 3: The cold war Another few months go by, and Megan and Matthew move back to the City and buy a house. As I mentioned, Matthew and Patrick have stayed friends during this time, so naturally Matthew invites Patrick and I over one day to see the new place. I feel a little anxious about seeing Megan (who I know has stayed Lucy's close friend), but I suck it up and accept that we'll need to face this eventually, especially with all of us living in the same City again. When Patrick and I arrive, Matthew welcomes us in and Megan.....is not there. A few months go by where Megan is noticeably absent from things, I observe that Matthew doesn't really bring her up, it is not assumed that she will join him if we invite Matthew out to get a drink, and I pick up what's happening - Megan has drawn a line in the sand and has iced me and Patrick out of her life out of loyalty to Lucy. Patrick and Matthew eventually talk about this to each other. Matthew in so many words admits that he doesn't agree with Megan's behavior, but also knows he can't change her mind. Patrick relays this information to me. The situation bothers me, but I feel at a loss as to what to do about it. Megan and I were never close, so it's not like I miss her and want a friendship restored. It's just awkward. Patrick and I spend a lot of time talking about this whole situation in the weeks that follow, and eventually I come to the conclusion, because of this and other factors, that it's been enough time that I need to reach out to Lucy and try to thaw some of this ice. I reach out to Lucy, we meet up, things are definitely prickly but I am able to apologize to her about how bad things got, and we reach some kind of mutual understanding. We text a little bit, a year passes, we meet up again to talk this through again and share life updates. We're nowhere near friends, but I at least don't feel like throwing up and running in the other direction when I run into her around town. We are Okay. However, through and after all of that, Megan's line in the sand remains. Patrick and Matthew have only gotten closer over the past couple of years since this has all "gone down", and because of this, Matthew has been pretty present in my life, too. We're not super close, but I've welcomed Matthew to our house many times for movie nights or parties, I've spent hours with him on day trips out of the City, we're definitely on some level of friendship. I will sometimes politely ask him how Megan is doing or she might come up in conversation every once in while ("Where were you this weekend?" "Oh Megan and I were at her cousin's house") but otherwise, we don't directly talk about this thing happening here. As this time passes, it does feel weirder that Megan still won't acknowledge Patrick and I's existence. But I know Patrick has accepted this as the way things are. It also seems clear to me from Matthew's passivity and sort of oddball nature that he's not going to bring it up or try to do anything. I find this frustrating because I like to address things directly, but I don't want to poke a sleeping dragon, and like I mentioned, I'm not sure what I really want from this situation, other than for it be addressed in some way. Of course it doesn't feel very good knowing that there's someone out there who's so opposed to me that they won't acknowledge my existence, but I know I can't change Megan's mind and I don't want my motivation here to be that I need to "redeem" myself in her eyes. So I'm stuck. I have talked ad nauseum to Patrick about this and he thinks that saying or doing anything about this is not worthwhile. He doesn't think Matthew is going to adapt his current way of being, and he doesn't think Megan would every change her mind. What do you think? Do I need to do anything, or just wait it out idefinitely like everyone else?

At the end of the day, do you in your 30’s, really need to be wasting your time with people who in turn, don’t have the time for you whatever their reason(s). You have explained what’s gone down & it is what it has morphed into to where it is today. There’s no changing that. You’re not on Megan’s radar but that’s her choice, but she still allows you to enter her new home in her absence! & Matthew? her Matthew is just being a straight up gentleman to you about it all. Lucy, your ex best friend past in all this, is still respecting you by acknowledging you to meet up etc. You need to put your efforts into enjoying life with Patrick & nurturing what you share with him & forget about the others who are quite happily living their own lives. He’s being loyal to you by standing tall & by handling the situation the way he thinks is best. His perception is two steps away from it as opposed to your face being hard up against the glass. The way you describe him, he’s stacking up to be a decent partner. It’s his actions that are doing the talking here even if you are bending his ear about the whole situation. If you like to address things directly, then take your thoughts further & forget about living in the past but rather, just learn from it all & get on with your life without looking back over your shoulder. In fact, it there’s any personal growth/experience to be gained from this situation, it will be your ability to just walk away from Megan’s drama with your head held high. Aye, be kind to yourself.
