Child support Question

My boyfriend has another child from a previous relationship. He’s been put on child support. He pays it when he can (he doesn’t work at the moment because he’s going back to school full time) I’ve been secretly paying his child support so he doesn’t get in trouble with the court system. I tried to tell him I made a payment once and he got pissed off so I told him I’d never make a payment again. Even tho the payments are being made the mother of his child is still ignoring him and not letting him see their daughter. (The mother of the child lives in Indiana and we live in FL)

She often writes him telling him she needs money and to send it via cash app and not through the child support system then she turns around and blocks his number and mine)

Am I wrong for making his payments for him?

Should I tell him I’m making payments?

Should we go back to court about the visitation?
