So this really has nothing to do with BP or symptoms, but I need to vent:

My sister and I are extremely close. We tell each other everything and we've never been judgmental or pushy.

My sister has the type of personality that if she feels you're telling her what to do or trying to control her, she will do the opposite of what you are saying and dismiss you even if you make perfect sense.

We have a little brother who is like a son to us. Between the two of us we raised him.

My sister, now recently divorced, met my brother's band director and even though he is in a serious relationship had an intimate relationship with him. This would not matter to me if it was not something that could eventually come back to hurt our brother.

The director's girlfriend and her family are very involved with the band and actually paid out of their pockets for my brother's membership fee (700.00) since he can't work, my mom is disabled, and my dad was laid off.

I warned my sister that yes, she slept with him and the damage was done ... but that it would be wise to stop communicating with the guy. He is always at his girlfriend's house and with the family. He is also much much younger than my sister and immature. He told his boss about the intimacy with my sister.

It's not like my sister wants a relationship with the guy, but she enjoys stimulating conversations and being able to "help" this guy with his family issues.

If that guy's girlfriend or her family finds out about their intimacy, my brother is the one who will get the blunt of the pain and he is innocent!! He can get kicked out of the band, he can be asked to pay back the 700.00, he can have the band members look at him differently and make his time there uncomfortable.

I told all this to my sister and now she feels like I am judging her and that I am overstepping my boundaries. She is really mad at me now and refuses to talk to me.

This whole situation is depressing me. My sister is my best friend and my rock. When I have any type of issue I could always count on her and vice-versa. Now I feel like I screwed up and should have minded my business.

Sorry for the rant ... but I needed to let it out ... Thanks for reading.
