Which is that, the last time we met, he confessed that he had a 'mistress' and had been seeing her for years and years (she called for a chat whilst I was with him). I was shocked, and said the knee-jerk, "But what about [his wife's name]?!" And he said, "Well, sometimes I think she suspects, but it keeps her on her toes - she makes more effort and takes better care of herself."
I was stunned, and very, very disappointed in this person who, in all other respects, is/has seemed like a wonderful man. I'm now meeting him tomorrow - he's recently been in touch and has invited me to a special occasion later in the year. I need to decide if I want to go and, also, tomorrow, do I be upfront and say why I've been out of touch over the last few years? I think I lost a critical amount of respect for him in one go, when he said what he did, and part of me feels I owe him this explanation, while the other thinks it's none of my business.
