Full disclose, my wife and I are 'separated' and moving forward towards divorce. We no longer have romantic feelings towards each other. She's gone on plenty of dates, and has admitted to having sex a few times. I don't mind her getting hers, and it's really none of my business.

As of last week I've been seeing a woman, nothing serious, but we've been sleeping in the same bed. Not going to lie, it feels great to get that attention, in a way my stbxw never truly gave me.

Tonight we have a getaway planned in another city, where we're going to be spending the night together and I'd like to push the envelope of our sexual relationship.

I'm fighting this feeling like I'm being unfaithful because I haven't had sex with anyone besides stbxw since we started dating 16 years ago. It's kind of guilty, but exhilarating, feeling in the pit of my stomach. Not going to lie it feels great, a guilty pleasure. No matter what happens I'm NOT going to disclose the details of anything to stbxw.

Anyone else ever felt that way? I feel like I'm finally being set free and living again.

Edit: I've never physically cheated on anyone, ever, in my life. I don't technically consider this cheating since we're separated, and she's already gone down this road.
