Well, this kind of happened to me in reverse a few months ago. A friend of alot of years (I hadn't really spent any time with her and we got together for a few days on vacation) thought I was evil incarnate because I had the audacity to vote for George Bush and have become more conservative. My personality surely has not changed, but I do believe she the victim role really resonates with her and she felt I had turned into an "oppressor".
She kept asking me if I wanted any of her "pills". I guess she had anxiety and depression problems and when I shared that I had gone through those feelings in the past...she couldn't understand why I chose to not go the pharmaceutical route. This kind of started our problems...I think she thought I was looking down upon her. Everything escalated at this point. It was bizarre.
So....maybe she thought my personality changed and I have become an ass. My take on it is that she is unstable, in a miserable marriage, a miserable job and was kind of jealous of my situation.
It freaked me out. But I realize she really thought this was my problem. Very sad. She would sit in the hotel unable to pull herself together, smoking like a chimney, rubbing cream into her face for hours while I went out and saw the sights. Then when we did go out together she freaked out at the crowds.
But in the end...I was the jerk.
So, do you know for sure that you are the one who is in the right in your situation? Just asking. I've gone over the bust up of this friendship a hundred times and pretty much know for certain that it was not my fault.
Well, just my 2 cents. It's sad to loose a friendship.
