I'm thinking of selling my boyfriends xbox/games to pay his rent
Can you think of any other way to come up with the money?
No, I can't think of any other way besides selling his things.
I know you are trying to come up with solutions, but you shouldn't sell other people's things without consulting them first. You shouldn't have to be responsible for paying for his rent, so maybe you should sit down and talk to him about how he can pay his rent himself.
I just wanted to make a point, he said I can't buy new clothes even though he dumps money into that stupid xbox
I can understand your frustrations. Though it's good to want to help your partner pay the rent, he should be the one to take responsibility here. If he wants to sell his xbox to pay for the rent, then that is ok, but you shouldn't be the one making that decision.
