Fresh Start?

So I have been with my girlfriend for 3years. We started going out in school, relationship was good, everybody was happy ha. Year later, summer before college, things went bad, I got kind of depressed,we ended up breaking up, or on a break, it was unclear. Within a week or two, she had been with someone else. She said she thought I didn't love her, she needed to try forget. I was shocked at how quick she could move on. I never stopped being in love with her, We kinda got back together for few weeks. Then after, around Halloween we stayed texting , she slept with a guy I knew fairly well. Again, I found it very hard to understand how she could do it, but I loved her. But I Hated what she did, crushed me 2bh. I tried to move on but couldn't really, I went off with one girl, not sex, but it didn't feel right. Long story short, we got back together, and have been together since. Things aren't great atm, I feel like she was more grateful I took her back than she never really showed me she really loved me. I felt like, when we going great she crazy about me but then, she can just turn it off, and have no problem been with other guys asap if we broke up or on a break. I Have a two part question 1) Can I forget what she has done, and have a fresh start, because I do genuinely love her 2) Is it odd, if she says she loves me, that she can go off with other guys jut after we broke up or go on a break? thank you.

Hello. I understand you're really bothered with your girlfriend's behaviour, because it's hard for you to understand her. But people understand and experience love very differently. The fact that she was able to move on quickly and you weren't doesn't mean she doesn't love you, she's just a different person and experiences feelings in a different way. Attempts to immediately find someone new even if for one night only, to distract themselves from the pain after breaking up, are not a very wise decision, but unfortunately that's what many people do, even when they can't get their mind off their ex anyway. Usually they do not feel real love to the new partners, because they still have feelings for their ex - they just seek affection as a way to comfort themselves. And your girlfriend seems like one of those people. If you broke up with her first and she found someone else later, then she probably didn't expect that you will be together again, so it's not like she cheated on you or betrayed you. Even though I see why you are hurt with her actions, I don't really think you can blame her for it. So I hope you can forgive her and start over your relationship, and I hope this time they will work out. Good luck!
