What if his ex is back in the picture?

ok this is a very long story...so to put the long story short this is how im going to explain my problem 2 you guys...while me and my boyfriend were getting 2 know eachother he had sex with his ex girlfriend. 1 month after that happend he asked me 2 b his girl, ok so its been 2 months since that happend and we are a very happy couple he loves me and I love him, but now his ex is back and she says shes pregnant. he asked her if she wanted 2 get an abortion and she said she didnt know what to do, so he gave her time 2 think about it, he doesnt want her back because shes too problamatic and she doesnt make him happy. he really doesnt want her 2 b his babys mom because he doesnt love her anymore. she's had 1 week 2 think about it and she still hasnt told him what she wants to do.
I know its not the babys fault !! but im just worried that she decides to keep the baby and ruin our relationship. please help !!!

Is this the same guy you had unprotected sex with and the same guy who lost his temper recently in a jealous rage? I think it's time you found a new boyfriend - someone who respects you and treats you well. For some reason it sounds like you worship the ground he walks on. He doesn't deserve that.

yea this is the same guy and I 4gave him because he cried a lot he stopped eating and he didnt want 2 go to school, he told my mom and my dad what he did and he was really sorry he wrote me a 12 page letter where he expressed his feelings and he apolagized like 20 million times, but is hard 4 me 2 let him go because I love him a lot

Ok well it's not just his anger problem -- what about his lack of responsibiliy regarding preganancy and STDs? He had unprotected sex with her, he had unprotected sex with you. Sounds like he still has some maturing to do.

I hope you don't regret your decision to stay with him.

thanks 4 your advice I'll keep everything you said in mind
thanks!!!
