Stupid

I'm nearing my wits end. She acts like a whore around him and she dumbs herself down. It shouldn't bother me this much but it does. When I say even the slightest thing she says that I'm ruining the "family atmosphere" when she acts like a hormonal teenage girl around him. Then she has the nerve to ignore me, because apparently the golden child can do no wrong. The worst thing is that I don't have my best friend around to talk to and to take my mind off it. I just  feel like I will end up doing something stupid.
