SOUNDS like the logical solution, 25!

SSMGuy, although you claim there are no problems except those generated around the lack of sex, those issues reach into many more areas. You describe a lack of trust, limited communication, your wife's stonewalling, your tendency AFTER 15 YEARS to drag her face in the muck with "self-deprecating" jokes about how you're not getting any, and your position that she is the exclusive source of this problem. Your claim that there is no residual bad feeling about her choices is not bourn out by the frustration you express--all has not been accepted and forgiven. I find it inconcievable that these negative attitudes & behaviours can be neatly separated from all your other interactions.
