Same. This was why I proposed separation to my partner. I don't want to feel guilty for going outside of the marriage even though I have been getting many offers lately. I haven't ever taken anyone up on their offer, but I have to admit that it's getting more and more tempting. While there is one person I am particularly interested in (and I think he is in me), nothing has happened. Separation is mandatory for 1 year where I live before divorce can happen. Even though we fit the legal definition for being separated, my partner tells me she doesn't want to be separated, but won't deal with her issues that are causing the strife in our marriage. I care about her, but I think of her more as a friend than a partner now. There is zero sexual chemistry between us. I don't see that ever changing until she gets help with her issues which she doesn't want to do.
