Old feelings coming back?

I have been with my boyfriend for 9 years. I can't say that he treats me the best - he's not physically abusive but can tend to be emotionally abusive and just snaps for no reason , when I have done nothing wrong at all. I guess this is a factor which is driving me away from him and our relationship. I do love him, I wouldn't still be here if I didn't, but I think I still have feelings for my ex. I was with him for 5-6 months when I was 15/16 years old and we broke up because we were so young, and he wasn't ready for a relationship. We have remained friends for the last 10 years. He was also friends with my current boyfriend, although they haven't spoken for the past 6-8 months after a falling out. I have been in contact with my ex through Facebook since they stopped talking, but haven't seen him in person and I really do miss him. I don't know if I miss our friendship or if it is more than that. He was always there for me and has witnessed how my bf treats me and has said things like he wished we never broke up, and he would never treat me how bf does especially with all that I do for my bf. I don't even know what I am asking, advice on the reasons I may be feeling this way, I suppose?

well you said your current bf is emotionally abusive to you. Coming from experience,when your in one of those its easy to want to look elsewhere for kindness and caring. I think you should break things off with your current bf because of the emotional abuse,try to better yourself first,love yourself more and realize you deserve to be respected and cared about,which it doest seem like this is whats happening or you wouldn't have gone to someone else in your past for reassurance.Once you are in a happy place I like to call it,lol,then see if you still have feelings for your ex on facebook not your current bf and go from there...its time to be happy right? lol good luck
