Brit
The irony is that despite being a passive guy myself, I don't think I'd ask you to go easy on him. I could say gee Brit go easy on the poor guy! I know though that even if you tried to see through your husbands passiveness which he still seems to have, eventually you'd run out of patience and leave him again.

A common complaint amongst "nice guys" is that no matter how nice they are it's never appreciated. I think its because deep down women mistrust nice guys, they somehow know that all the niceness comes with a covert contract.

"I may not be very attractive but I'm nice to you so I expect you to want sex"

I guess what I'm trying to say is that unless he manages to change himself you just won't last with him. One of the keys to successfully DBing is working on yourself so as to not make the same relationship mistakes. As an LBS not only is he not working on himself, but making the same mistakes with another woman.
