The Father

elizabeth
So, I'm really not posting this to be told I have feelings. I'm posting because I need honest opinions. 
The father of my baby is my friend. We've known each other for awhile and only started hooking up a few months ago. When I told him I was pregnant he reacted as expected considering this wasn't planned and we are not together, but he also surprised me. He did say he couldn't be a father and doesn't want anyone to know that he is the father (which I expected) but I honestly expected him to lose his shit on me and completely write me off as well. He hasn't. 
He understands that I am ultimately doing what is best for me, even though he doesn't agree with it. He's told me he just wants me to be happy. He checks in on me from time to time (see how I am feeling, how my appointments/tests have gone) and yes, we've occasionally still been hooking up. He's adamant he'll never change his mind. He has said he's not sure how he will feel once the baby is here, or even once I start showing. We are still basically being friends, our relationship hasn't overly changed. 
Obviously I am holding out hope that he will have a change of heart, and I know that's a really stupid thing to hope for. I guess I'm just wondering how many have been in the same, or similar, position and things did change. 
**to clarify, I am hoping he has a change of heart about not wanting to have a relationship with his child. I do not want him to all of a sudden want to be with me. I am hoping that my child will grow up with him as the father, but I know that is not what he wants**
