I've wasted my time

So after being in a relationship for 4 years I have decided that I will tale my son and leave. Im not worried about fighting over custody because my son's father wouldnt even look at a court house. He's that lazy😒. I dont want him raising my son because he doesnt know how to talk to him or me. He talks to me reckless in front of my son. He calls me bitches & hoes in front of him and he doesn't know how to hold a decent adult conversation. Everything is a game to him😤😤😤. I fell out of love a long time ago and i was blinded because I did love him and Before I gey to the point where I hate him im just trying to leave. I have no support from family its just me. So with that being said I only have myself and Im willing to leave and not look back. As of right now I don't have the funds and I won't have them until a few weeks. We barely get along and im not trying to get into a physical altercation with him while I have my son. Im just ready to leave.
