My 18 year old brother has been dating this girl for a couple months, though they were close friends throughout high school. Ever since they started dating, my brother has completely withdrawn from talking to me, and has just generally distanced himself from our family. Now, we live together, so here's where it gets annoying. She's constantly over the house, using our facilities (shower, laundry etc) and does not say a word to me. Not a hello, not a hey how are you, whatever. And then today she has the gall to text me and tell me to "stop using her body wash." (Suffice to say, I've never touched her flipping body wash.) This is the most she's ever said to me. I don't know what my problem is exactly, but I really resent this girl, and it makes me feel dumb as hell. I feel almost as if I've lost my brother, and gained two aloof room-mates who don't pay rent. They both work together, and spend nearly every second together, and yet my brother can never come up with rent or get another job. To me, it seems like he's in a codependent relationship with a possibly controlling person. I don't know how to address the situation with my brother when I feel so emotionally estranged from him, especially since we use to talk so much and be somewhat close. Help please.
