I commend you as well...we show people how to treat us.
I know you stuck up for the boy...but it shows your character and your unwillingness to tolerate "abuse".

Yes, my b/f brother is a bully...sounds very similar to your situation. My boyfriends brother is the "boss" of that family..and he demeaned me one day..and I said... I need you to remember I am not your brother or your mother..you can't talk to me like that.

He didn't know what to say..but now every family event..he and I tit for tat...with him always being the one to start it.

Hes even been so awful to say "you are a little bit of a crazy *****"...get your medication adjusted..which made me want to punch him in the face..and his brother wasn't there...he sent it to me in a text.

I did tell my b/f...but he didn't say anything about it...it pissed me off...but I understand why he didn't..

Just let it go...take the higher road..you said your peace....now go into the family situations without grudge and hopefully he doesn't have one either (adults).
