OP, if it feels really good/right/special in the present, and that’s your chief reassurance to us, consider that the pleasure in the moment also comes with overindulgence with a bad for you woman, too much food, alcohol, and drugs, both prescription and illegal. Feels so special is the mind/body/heart trap on the way into a bad relationship, fatty foods for the guy on the way to a heart attack, sweets for the eventual diabetic, drinks for the guy who is fun at the party then becomes abusive to loved ones, drugs fir the high that morphs into addiction lost job, lost home, family and self respect. You will do what you want, as any addict does till they come to grips with their addiction. No idea who you are in person, but from afar, I wish that you would do the most self respecting thing possible and walk away from your drug of choice, the embrace of that married woman with kids. You will improve many lives in the process. Then, knowing your addiction, choose wisely, starting with unmarried, then also truly single, as in a woman not in an unmarried relationship. Do something less pleasurable. It’s a healthy sign of a free choice, ungoverned by present or anticipated pleasure.
