I agree with you that Hairdog needs to have "The Convo" with the W, but in HD's defense, he HAS been honest with her. Not too long ago he did tell her that he wasn't going to stay in a celibate marriage forever. He even refers to that comment in the first post on this thread. So, he's a little further along than he thinks he is.
Hairpup, listen up. You have a perfect opener with W's latest email to you. You told all of us that if no sex happened on your vacation in Wisc., you were moving to the basement. Not that I think you should do that this instance or anything, that is solely up to you.
But a simple statement like the one you made: "I don't know if I see myself in Wisconsin in 5-10 years when I can't even see me in the marriage a year from now..." is a nice segway to some major shakeups in the HD household.
It's scary, so I don't want to push you in any way. You'll take action when you are ready. Don't do it a second before. You understand boundaires and you understand Mu... when the final straw falls -- and you will KNOW when that happens -- you'll be prepared.
