What should I do? (Problems with BD)

Am I wrong for responding this way? I just want to protect my son. His father stopped helping me financially this month and still tries to dictate what happens with our child and I say no. I’m a full time nursing student plus I work and no one helps me with our son. I do everything by myself and pay for everything including $200 daycare.

His family tried to force me to get an abortion and I refused leading to months of abuse while I was pregnant from him and his family. They all apologized when it was around time for me to give birth and I let them meet the baby and get involved. To me they are asking for too much of me.

My BD cussed me out all the time and rages at me then always storms off. He always apologizes and I get back with him but he never changes his ways.

What should I do?
