I've not spoken to my brother in over 13yrs.
We were both adopted together by same approve parents, he was my adoptive mothers 'chosen' one.
I had an awful childhood with him and my adoptive mother.
13yrs ago, the last time I saw him. He made an attempt to treat me with respect. Even admitted he knew what was going on between my adoptive mother and I. Said he'd often wondered what life had been like if he'd been me, and not mums 'favorite'. The fact he knew all those years unyet heaped on the torment, was more than I was willing to forgive. I didn't want his respect, his friendship, his 'brotherly' love. I walked away from him. I've not looked back. And this is after working on this stuff in therapy too.
I have no guilt. I'm not responsible for his sudden change of heart. That's bergen him and his whatever.
