man i feel your pain. im in the same situation & so is my other roommate, theres 4 of us. 2 in each bedroom. my roommate & his both have their gf's over like 24/7 & it gets so irritating. all i can say is wait it out. thats what im doing, next year its me & him in a room & both of us have gf's that live 3 hours away. & the other 2 guys wont be living with us, so we kinda just deal with it for now. sometimes you find out some friends you just cant live with.
