It sounds to me like your ex is very immature and selfish to say the least. I'm so sorry you are being hurt by his callous attitude towards you and his child.
While the thought of having him as a loving father with your child is a good one, I think you might want to change the course of your efforts and put them directly towards yourself and your baby.
Since you obviously can't change who he is or how he reacts to your situation, you only have control over yourself. I don't mean you should cut him out of your lives completely. What I mean is that you would be much better off if you did what you need to do to care for yourself and your child. Let the chips fall where they may. Don't make excuses for him and his bad behavior. Accept it for what it is and know that you and your baby deserve better. Don't bang your head against the wall trying to get him to "come around and get it".
I saw my daughter go through some very difficult times with the father of my grandchild. He no more wanted to be a father and involved with his sons life than a stranger off the street. I saw the hurt and devestation in my daughters life from her putting so much effort into the relationship (whether they were together or not) and it just sucked the life out of her. I don't want to see that happen to you too hon.
Take good care of YOU and that precious child you are carrying. Your ex will make his own way on his own terms and there is not a thing you can do to help direct him. It's all his call.
Much love & respect to you!
