He left me at 5mnths, now back at 9mnths

So SO of almost 2 years left me in beginning of April and didnt talk to me or see me for weeks...now that I'm 9 months pregnant, due Aug 1st, he's back and after all the tears I have cried and the depression after him leaving me...I do not love him or can even imagine a life with him. Why, so he can do this again to me? I wish I could love him, but I don't. I look at him and he disgusts me. I long for a real love with a real man...not a coward. But am I supposed to at least try and make it work for the baby's sake??
