She can provide it, because she did it before. What the truth is that she is putting much of her attention on this other male, or herself and she's not giving it to you. It doesn't take much time, and even small amounts of time and attention she is not willing to give you.

Well she use to tell me it was no big deal to spend 20 or 30 minutes a night having sex. Then one day it became this giant deal. I have no idea what changed.

What helped me is "What would I tell my son in the same situation?", "Do I want to teach my son through my inaction that this is OK, that it is OK for a woman to treat him like his mother treats me. Or is it, I'm that lowly of a man that I don't deserve mutual respect, generousity and a loving relationship?" [/quote]

That is what makes all this not so cut and dry. I have kids who IM trying ot teach life lessons here. Which one will they get? That dad has no spine, or that dad didnt cut and run when things got tough.
