I'm not advocating that he abandon his children, but I think it's healthier for a child to have 2 parents who love them and are happy than it is for them to grow up in a home watching their parents...

Thanks!

While somewhat humorous, that's not really helpful, nor is it true.

I wouldn't want to be with him if he was in an open relationship, I'm not interested in being the other woman. It's possible that you are correct that he is using me emotionally, but he has told me...

No, not at all. He made it obvious long ago that he wanted more, but I said that I didn't feel comfortable doing that unless he leaves her. He respects me and has never asked/implied that he wanted...
