hey i remember reading your post. it sounded like everything was gonna go ok. but from what your saying it seems like hes the type of guy that yea he'll be there financially and emotionally for you (because you guys are JUST friends) but he feels that he has the right to make his own life with other people.
your getting attached to him because you thought that he would magically fall for you and suddenly turn into mr.mom just because you ended up prego. when its between friends and that happens it rarely turns into anything more.
if i were in your situation, and mind you this is my own opinion i would have the baby, but i would end the friendship with him. cut off all contact, go to court and gain full custody of the child and give it my last name. shoot if i had to move i would. if you stuck around it would only get worst emotionally for you and your kid.
obviously and im not taking the guys side, he has the right to date other people just like you have that right as well. because you were just friends hun. im sorry your goin through this but its better to face the reality straight on than to try to change someone
