I have a 25yo daughter moved out 2 years ago. 30yo son had to move back due to divorce. Not working at present but in process of starting new job wfh. Told 25yo we would like to move brother into larger room to accommodate for this and she has gone mental. Explained wouldn't throw anything of hers away but as she only comes home couple times a month and he will be paying rent and due to his circumstances he should get the larger room. She has now said she won't give it up. We are putting him before her and being we are unreasonable and if we give him the room she won't come back! I'm aghast. Surely I'm not being unreasonable in the circumstances? We try to give them as much help as possible we're currently paying off her car for her and she says we're favouring him..
