Precariously perched on the edge of a precipice

Ugh. Where to start? hmmm... lets see. I am so frustrated with Michael right now. I haven't seen him for two weeks because I've been on nigh shift for the last 14 days - usually working 12 hour shifts. On my one day off he calls me and is like, "Umm... I don't really want hang out today. I think I'm just going to go home." My one day off and I now have nothing to do because Michael doesn't really get it. Not to mention I'm probably not going to see him for another week because of work and family and what not. I'm so frustrated, I know that there's something else that made him cancel on me today - I hate the fact that he won't tell me what it is, and leaves me to my own speculations. And that's not the worst of it. One of my good friends, or at least thought of her as a good friend, tells me I should break up with the aforenamed guy because she wants him for herself. At first I didn't know what to do - what to say. I was shocked beyond belief; I almost didn't believe her. Not only that but she constantly flirts with him and hits on him. It's one thing to flirt with a good friend (all in jest of course) but another to be so blatantly obvious that everyone notices. Worst of all she probably doesn't even know what she's doing. She touches him all the time; either on the arm or offers to give him back rubs and the like. It's driving me nuts! I am angry at her for doing this, angry that she can't contain her own emotions and angry that she can't keep her hands off what isn't hers. God, this is giving me a headache. I don't want to see her right now - mostly because if I saw her I know I would say something to her that I would regret later. I don't even want to go to church in the morning. I know I will end up saying something snippy to her or at least a biting remark. Damn, this is vexing.
