I just want to be alone

I don't want to be in a relationship with him he has done so much to me caused so much pain that I'm just feeling so numb now. He's cheated he tells me that I need to take care of myself. I just feel like he wants me to just be at home and e takes care of us I mean I'm happy he does but I want to be independent I want to get my own money. He's had a hard time watching our son. Now he just wants me to quit my job. I've told him to leave like 3 times but he just ends up saying he wants to work it out. Like seriously idk tf to day anymore... Like I want us to be a family. I'm just not happy anymore
