Advice

My ex feels like me putting him on child support is the end of the world. He wasn’t crying when he was putting his hands on me or staying out all night doing who knows what. He messed me up mentally and I feel like what I’m doing isn’t so bad. Yeah he says he will pay but how can I trust that if I don’t trust him. He says I should show him I could do it on my own. And that I’m only doing it to get back at him or to help benefit myself only. I just want opinions I guess.
