Today, Friend had a tough day taking care of Kid, so she asked me for a hug. Well, I'd had a tough day at work, and I could use a nice hug myself. That hug turned into a bit of a makeout session. I feel bad that it happened because my wife was not home, but I had told them that they were free to explore their relationship without me, so wouldn't that imply that it's okay for me and friend to explore our relationship? After all, I wasn't there for the first kiss between wife and friend, and I haven't been asking what they have been doing up in friend's room. I guess I feel bad that I didn't get clear permission first. Or I feel bad to be with someone who is not my wife. I don't want to hurt my wife's feelings. The only reason I'm involved with this woman is because my wife loves her.
