Is AUTHOR wrong in the post ? POST : So my brother recently started dating this girl he’s been trying to get for four years. It’s been a month and they are already in love...I’m happy for him, he’s not depressed anymore and that’s great, but we live in a two br apartment and we share a lot of space. 

Recently his gf has starting spending the night and coming over while he’s at work which is making me feel uncomfortable in my own home.  I don’t know her, or her two kids she brings over...I feel like I’m stuck in my room all the time because of it. So I asked him to tell her to only be there when he is there, which he did, he agreed that we each pay rent and I have the right to be comfy in our place when he’s not there. 

The problem was that her reaction to this was to just not come over ever, she does his laundry, cleans his room, cooks dinner for him to come home to, wifely things she says...they got in a huge fight about it and now I feel like caving and just dealing with it.
