I usually lurk in this forum, but couldn't resist.
WNC, you sound as if you're a Doc Love subscriber. I just calls 'em as I sees 'em. Doc Love has his shortcomings
If you don't know who Doc Love is, check out www.askmen.com.
A-man, the confusion there with your W wanting you to pour your feelings out and then tells you to shut the F up is confusing. She probably is looking for some validation somewhere, and may be picking up whatever you say to her as criticism.
WNC does have a point. Change your R bit by bit (this takes time) by becoming interested in other things too. Don't focus so much on the W or your M. Make your life more interesting and see what happens.
Now... as I always say... my M died a nasty ugly death and I'm D. But sex became an issue for us... and my H went way off on the deep end. However, one of my biggest issues with him was just his lack of interest in anything other than his stupid computer and mundane stuff around the kids and the house. Became a vicious cycle. I began to withdraw more... started working more myself, started traveling a lot, became less available in a negative way. Just a hint: try to include your W in on more of your more interesting activities. Don't beg or whine or plead... but see if you can spark an interest there.
