My close friend of 10+ years confided in me recently that she's been having an affair with a married man for the last 2 months.
We've always been close but due to work and other commitments we just haven't seen each other very much lately and decided to have a catch up over the weekend which is when she told me. It made sense as she has been more quiet than usual, slow replies etc.
Apparently they met online, some dating app I think. He only lives around the corner from her with his wife and kids.
Is it wrong that my opinion of her has somewhat changed?
I feel guilty for some reason, maybe because we've been friends for a long time and she's not actually done anything to hurt me but I still think it's a shitty thing to do to someone else. I've never taken an interest in married/taken men myself and I don't really understand the appeal. I guess she sees something in him though but I don't think it's love, just an attraction or something.
