So depressed

My baby's father has another child who is 9 months old.. He finally spoke to me at 20 weeks being pregnant saying he wants to help me. When I told him he will pay child support he said fuck u and the baby then I'm moving to Hawaii to be with the son I actually want. I shouldn't have been involved with him in the first place and I know I shouldn't even want anything to do with him but it breaks my heart to hear him say that and to know my child won't have a father. I can't stop feeling sad and I know it's bad for the baby I need to stop feeling this way 😔
