I have been close friends with another couple for 20 years. In fact, the wife is my best friend. About 10 years ago, she started treating her husband in a way that disgusts me. She's not physically or verbally abusive, but she does exploit his natural goodness. For example, she doesn't work or keep their home. He does EVERYTHING for her and their children. She claims to have a health condition, but she seems to be healthy enough to do fun things. Their marriage is also sexless for the past 3 years.
I came to visit them last year and was shocked by what I observed. I tried to help the husband out, but the wife would not let me. I've barely been able to talk to them since then, let alone visit again. Worse still, I think that I've developed feelings for the husband. I would never do anything to act on it, but I'm torn.
