I'm a little upset at the moment.

So there's some bull shit going on in my house right now, with my mother being the center of the problem. She has this boyfriend who happens to piss her off a lot. She even suspects him of cheating. Yet, instead of just breaking up with him, she decides to have a "friend" come over. She fucks him and then calls her boyfriend the next night, as if nothing happened. When her boyfriend starts upsetting her, she starts giving these stupid hints that she's screwing someone else. She says "I'm being taken away from you and you don't even know it." 
It's the most disgusting thing. I'm upset because my mother has to be such a cheat whore. Then she has the nerve to have an attitude with me for no damn reason. Just because you're fucking different men doesn't make you this big shot queen. All it does is make you a dirty whore. 
I feel like throwing up. I don't want to look at her or speak to her. 
I just had to vent for a moment.
