I wish I had my own place!

Lately, my brother relationship has been ticking me off. His girlfriend is in our apartment 24/7. She has her own apartment but never goes home. um even when I was in a relationship that annoyed me. I think it's getting to me more because at times I want to be alone and naturally my brother's scheduled would allow me but she's here. The moment my brother goes out the door I'm like, "oh, thank god" I turn around and she's right there in the den. Her crap is all over the place, purse on counter, bags on floor, stuff on couch; It's rude. I find it rude she doesn't talk to me (good morning, hello). She very antisocial and I've been trying to understand but I'm so use to how friendly the EX-girlfriend was. It's night and day. This one lie, cheats, and I think my brother is settling. Not my business but I'm tired of seeing her. I cannot wait till May I want to be done with this apartment lease.
