Is my boyfriend trustworthy enough for me to take another chance?

I felt like my bf was becoming more possessive and controlling so I told him I need a break to think things through. Since then, he has promised to be more sensitive to my needs and give me as much breathing room as I want/need. He sent me a dozen red roses and lots of communications how about how much he loves me, etc. I just don't know if I can rely on his promises. Maybe he learned a lesson or maybe not.

Hello WeatherGirl, I'm no expert but I'll give responding a red hot try. First thing I noticed was this comment from you: I felt like my bf was becoming more possessive and controlling Possessive and controlling is a serious issue but the 'more' concerns me the most. It implies this isn't new and he's been this way towards you for some time now. Yikes! In what ways has it been? and In what ways is it getting worse? Trying to figure out exactly what we are dealing with here so please feel free to elaborate. Hope you're not feeling too down. I'll be watching for your response. More info needed.

My bf has shown a pattern of being pushy/controlling and also unaware/do not care about other's feelings and needs including mine. He can be egocentric (per my therapist). Long story short...been together a couple of years and his pushiness really got to me and I told him i felt suffocated and pushed around and needed a break. Not sure how long a break should be but I figured a few weeks. Problem is we are invited to 2 consecutive weddings in the next 2 weekends and I just don't feel ready to give him another chance and not sure I ever wills so I told him I wasn't going to the 1st wedding of his friend and I was going alone to the 2nd wedding (my friend) alone. He freaked out - he has written me "love letters" via text and email, begged to meet and talk in person, sent me a dozen red roses, etc told me the only thing that's important is for us to be together and he'll do anything to make it work etc.... I told him I didn't like his selfishness a few months ago and he told me then to give him another chance and he'd change. He did get a little better at that issue but then the pushy/controlling part started in again. We do love each other but am I kidding myself about his behavior? if we get back together is it realistic to expect he will get pushy in a just a matter of time or is it possible he will change. I greatly appreciate all of your input. Even though I have a therapist, I find that sometimes is helps to reach out to folks who may have actually experienced this type of thing. I just don't want to throw away a relationship it took a few years to build nor do I want to stay in a harmful relationship so I suppose want some reassurance if possible. In any event, my bf is not contacting me per my request (and he is going to the wedding w/o me) but I do need to make a final decision soon since there's no point in dragging this out either way. The email he wrote me saying he'd change was quite detailed and said essentially he'll do anything to stay with me...his "push" for us to live together will not happen again unless and until I'll be ready; he is willing to adjust his life so I'm comfortable, etc. While the email sounds great, I don't think I can trust him to actually follow through. I think he's just saying what he needs to now to avoid me leaving him altogether. But maybe I'm wrong? The other issue is what I perceive as him feeling somewhat threatened by my adult children. He seems to feel insecure when I'm with them and not him, even though I've given him no reason to be that way. The email addresses this and states he knows my kids come first and he wants the opportunity to get to know them better so they don't feel threatened by him (but he doesn't address his insecurity). I know there's no way to know for sure if the decision I make is the right one but I want to make the best decision possible for my own mental health.
