Is it okay to fall out of love with your baby daddy?

I just don’t feel the same anymore after all he & his family put me through. Now I feel bad because he’s so deeply in love and I’m just not feeling it anymore. So tonight I decided to take a ride with a friend and he totally spazzed on me which made me even more disgusted with him. He’s so insecure and abusive when I’m not pregnant, because I’m currently pregnant now. I know this is all over the place but can someone tell me it’s okay to fall out of love with your child father? Because I’m feeling bad about it
