Am I in the wrong?

So me and my boyfriend were talking and he asked me if I’ll make a cash app for him. I said no because I ain’t gon find another reason to fuck up my money (I usually do). To which he replied “make it” and I said “no.” again. So he tells me “fuck you.” And I was like “okay.” he went on to tell his brother “I don’t have a girlfriend she won’t even do that and it’s JUST MONEY” and I was like damn. Really? I got mad because I shouldn’t feel obligated to make an app for him. Idk am I wrong?
