I'm so sorry Kim... I agree with Candace that you don't need to relate certain things to your brother. if he's just going to be a jerk, then why put yourself through it?? He should be a support for you, not someone to tear you down (don't ask me why I don't give this same lecture to myself about my mom...).

Big hugs coming to you! You were lucky to have your "adopted dad"...

Things will get better... it just takes time.
