Getting paid to stay in a toxic relationship

I know what you’re thinking but HEAR ME OUT. Should I take this mans money. My baby daddy was messaging some girl on his Facebook and deleting it and I called him out on it and told him I didn’t even wanna be with him Bc he’s done this before and he was totally trying to cheat on me. Sooo after that I made a joke saying that I don’t even think he could pay me to stay with him. He said he would... and like I have a baby that’s 3 months old so I might take him up on his dumb 200 a week. I really need help leaving this relationship, I always go back but while I’m working on that why not make make money.... ?
