<human>: Summarize the given text in a few sentences.

My brother [23 M] and I [25 M] got an apartment together about five months ago, around the same time he met his now fiancé [22 F] and wants her to move into his room and only have to pay 1/3rd of the utilities when they get married next month. The apartment we have is pretty nice (a 2 bedroom that costs around $1,200 a month), and I just don't think that that's fair. Luckily, I have to sign for anybody to move in, just like he would if I wanted someone to move in.

He thinks that because she's going to be his wife (he's very 1950's about the whole marriage thing, he doesn't even want her working...) she shouldn't have to pay rent at all, and also because technically she will be in his room, so rent should still be half. I think that's a little silly; she's going to be living here, she'll be using the living room too, have clothes in the laundry room, invite friends or w/e, the point being she's not going to be a hermit in his room 24/7.

I on the other hand think rent should be split into thirds, as well as utilities. Three people = three portions of rent, easy as that. Am I asking too much? Should I ask for less, nothing at all, or stick to my guns?
<bot>: My brother wants to have his brand new wife to move in our 2 bedroom for $20 a month. We still have another six months on the lease.
