This is fiction, I'm not married and have no kids, just making up a case for the sake of the question. Learn what? She's the one cheating, and with npt just one guy, but a multitude! Most of them were complete strangers to her! It was four years of what I thought was a mutually blissful marriage down the drain in one night. I don't know how long she's been doing this, and can't even know if the children I was raising were really mine! I married her because I think I got her pregnant in high school, so I married her because I loved her, and still do to a degree. She says shes sorry and that she loves me more than anything in the world, even her own life, but I'm having issues believing her. She's telling me she's a sex addict and that she's been doing this because I'm working late so often, and too tired after I come home, porn and masturbation weren't doing it for her, so she got tempted into cheating, next thing she knew, she was hooking up with strangers online for sex, and far from normal sex too, by the looks of it, her libido was thoroughly jewed, she wanted to do the stuff she was seeing on those internet videos. She was doing this while our kids were in school or at camp, during the lockdown she found other ways to sneak off. I caught her in one of her lies and looked into it I secret, then came home to find another man who I'd never seen before answering my door when I came home, and he told me everything.
