My brother/abuser is moving back in again ("short-term"---but isn't it always??).

Someone tell me this isn't happening! I was just starting to make progress in talking about the abuse. Every time he moves back in, I backslide. I clam up, isolate, get more depressed...this isn't fair!

I only have a month left. Doesn't seem like that much, but couldn't my parents make him suck it up and make it on his own for that long?? He over-exaggerates if it suits him (he's a sociopath), and always comes running to mommy and daddy whenever life gets too hard. He's lost like 5 jobs in the last 6 months--no joke. He's almost 20! I get not wanting to shove him out of the door right after his 18th birthday, but when does it get to "grow the f*** up and take responsibility"??????

This makes me so MAD!!!!!
