Is AUTHOR wrong in the post ? POST : A friend met a married guy about 3 years ago. She dumped her boyfried and started dating this guy. I initially thought he would divorce his wife and they could continue their relationship like a official couple. The thing is, he didn't. 

My friend absulutely hates the wife, is calling her names and makes fun of her behind her back. I usually defend the wife, (I don't know her, but feel really sorry for her) since she is the only victim in this mess. My friend absolutely delusionally believe that she is his "one true love". The guy has no intentions on getting a divorce and the wife knows nothing. They don't have any kids (yet) but its still just beyond shitty.

My problem is that, allthough my friend is as nice as usual to me, this situation just makes me dislike her. I feel that she is showing a shitty white-trash personality towards other people. My respect for both of them is gone. I feel guilt and anger everytime I see his poor wife in town. Both my friend and the guy has no moral problems with cheating and dont't seem to be bothered by any guilt. 

The last two moths I simply don't answer the phone when she calls (she calls a couple of times a week and the conversation is usually about him being an asshole and me telling her to dump him). My plan is not really to ghost her. I just need to get my mind straight about why I'm dumping her.

Am I the asshole for dumping a friend about something that is actually none of my bussiness? Am I the one who need to take a chill-pill?
