I am always perplexed by people like your W. I truly think it is even more selfish to deny sex/intimacy to your partner than for the HD S to go outside the M for sexual fulfillment (if the S is unwilling to make change of course). Intimacy/sex/love is a wonderful part of life that should be experienced within a M. YOU are not the one with the problem, SHE is. Unfortunately, her unwillingness to even discuss the issue puts you in an awkward position for sure. I'm sure you love your W but if she is never going to have sex with you, can YOU live with that decision? The fact that she says she will leave if you will not let her get away with this selfish decision is actually the right thing for her to do. But why does she need to take the kids out of state? Just to be difficult?
