I'm moving house next weekend with two people - one very good friend of mine (M, 24), and a girl I hardly know (19).

There are 2 very nice bedrooms, and one much smaller. We are approaching the time to negotiate, but the girl is making things difficult ("I'm too hungover to talk about this", "Can't I have the nice room cuz I'm the girl?"). Any advice for negotiating something like this with a woman? It seems like appealing to logic isn't working (ie. "We need to sort this by Friday you stupid bitch, of course we need to discuss this ASAP.")

I'm getting this really sickening feeling that I've already made a huge mistake here....The two outcomes I want are either:

  1. The smaller room gets a sizeable rent reduction (in which case I'll take it)
  2. I get one of the two nicer room.

Any advice would be much appreciated. I don't care about ethics/morals whatsoever - I just need to be sure that I get a rent reduction, or a big room. If any more info is needed, fire away.
