Its funny, this disorder we live with presents so many different faces. When we are well, we are completely normal, there isnt a visual sign of the problems we have. So people assume we are fine and forget what we deal with.
My mom can be the same way also. I love her but she also wants tons of stuff when i come home. Then she wonders why i dont come home often.
It may be his house, but there should be rules that he abides by. Calling first unless its an emergecy before he comes in the house.
Does he have kids? Cause i havnt seen one kid take good advice from their parents. LOL LOL LOL Of course kids mess up, how else will they ever LEARN.
My ex still lives in my house (i live in an appartment) even though i own it, until she has to move i allways call and check if i can come over and visit thor, or do work on the house. It may be mine, but i respect her privacy as an adult. Your brother should give you the same.
