I want to use my boyfriend and I's joint account to help my mom with a bill
Does the money have to come from your joint account?
Yeah it does, I put all of my money in that account now so it's the only place I could get it from.
Wanting to help your mom is great but since it's a joint account you really do need to talk to your boyfriend first. It would seem greedy to just take money out without telling him about it and he'll likely get upset.
No, I am tired of him getting to do whatever he wants, its my turn.
You really need to communicate this with him. You could bounce a check if he spends money like normal and that would be really bad.
