You can only workk on youirself. You have absolutely no control over the wife. So her is what I understand MIGHT work, you change yourself, make yourself more attractive. Then you get rid of all the marriage busters. Then you meet her needs. Then you tell her what YOU need.
Now the big problem, if you do all the things above, then the hope that all marriage counsellors have is that the womens "natural" sex drive will return. So if the problem is totally relational, you might have a chance of raising her to HD. Unfortunately, I believe that for most LD women, the true underlying problem is physical in nature, and most likely they have absolutely no clue as to what it is or how to fix it. And if she suffers from arrousal disorder, you might as well kiss your butt goodbye, she will NEVER be HD again.
