So me and my boyfriend have been together for almost 3 years and in those 3 years,he broke up with me after our 2 year anniversary of being together and at that time I was pregnant but no one beside him and my best friend knew,he broke up with me for about 4 months and in those 4 months he was out of control partying and I found out that he had sex with over 30 girls which most were unprotected because I later found out he gave me chlamydia during my pregnancy he would tell me he wanted to be with me and sweet talk me and then the weekends he'd be screwing around with some other chicks, but now it's been about 5 months since we've been trying to work our relationship out but I just can't forget all that he did to me he made my pregnancy hell and even now that he's been trying so hard to work things out with me. Like I know he really is trying his hardest to prove to me he really wants to be with me and my son he's been faithful he's stopped his partying he always with me but I just can't seem to move on and it's ruining my relationship with him I just don't know what to do?

You can't forget his past, but can you forgive him? He sounds like he is trying to be a good father and boyfriend. It may take some time. It is up to you to decide if you want to go to counseling to work some of your issues out. If you can't trust him, then it will never work out.
