My friend is friends with a woman who cheated on her husband with a man she dated before she got married. She left her husband but the man didn't leave his wife. The affair has been ongoing for well over a year now and she's still seeing him off and on. They're in their late 50s.
My friend organises enjoyable activities and wants the three of us to do them together. Some of these are overnight trips and the friend's friend does enjoy talking about her troubles in a very "woe-is-me" way.
Would you want to spend time with this woman or would you tell your friend you'd rather do things separately? The activities are a lot of fun but I don't like implicitly condoning the affair and wouldn't like to be friends with this woman as I don't respect her.
