head pains

why is that when arguing over needing sleep I don't get sleep? I wanted to go to bed about 10pm and here it is 2am and yet I can't sleep b/c my possible g/f wanted to yell at me for not giving a shit about being a trophy to show to her friends that don't give a shit about me and 8/10 of them want in her pants. So really, truly, why does this happen. I ask for things that are unreasonable apparently, as a "grown" woman she be able to deal with minor things on her own and not just ignore them, or require others to fix them for her, be able to know what she wants to do, eat, and where to do/eat it at, when she has the time run and do things I don't have time for, but affect both our lives. However, the fact that she wants to sit on a couch and do something entirely away from me, with me their constitutes as spending time together, but if I want to stay home and sit on the couch and do something other than watch her it doesn't????? confused am I. Two days is about as long as she goes without yelling at me, from the morning to the afternoon, her mood is entirely different. Why? who the f' knows, but apparently it's my fault, b/c I am the one to get yelled at.
