<human>: My wife Anne and I have been married for 15 years.

For six months, I've spent a few hours a week with one of our single friends, Becky. She's been going through some tough times. Every week Becky comes to our house or I go to hers. We have coffee and talk. I've helped her make some tough decisions. Anne is aware of this. It's not a secret. Afterwards, Anne and I talk about what Becky and I talked about. Sometimes, Anne comes home from work while Becky is still there, and she joins us. If Becky were one of my male friends, this would not be unusual.

The problem is this. I think I am developing feelings for Becky. I now think about her every day, many times a day. I doubt Becky has such feelings towards me, although I do not know.

I think I know why this has happened. For the last 10 years, Anne and I have not made love. She has a medical problem that prevents it. It may be treatable and we have good insurance but she has not sought treatment. Anne is afraid of doctors and the treatment would not be pleasant and might not work. Our relationship is okay otherwise, but has been strained by this. Since I cannot make love to Anne, I tend to fantasize about making love to other women. And lately I have even thought about Becky in this way. These are just fantasies, but they make me feel guilty. (Becky does not know about Anne's medical problem, or this issue in our relationship.) 

I care about Anne very much. I feel guilty about my feelings for Becky, and have not told Anne (or Becky) about them. At the same time, I greatly enjoy spending time with Becky. Talking with her is often the best part of my week.

I do not want to hurt anyone.

Has anyone else gone through anything like this? Does anyone have any advice for me?

Can you provide a brief overview of the text?
<bot>: Wife and I haven't made love in 10 years due to a medical problem, but otherwise our relationship is okay. I'm feeling guilty because I've developed feelings for a friend who I've been spending time with.
