Couple months ago I met a woman who works at a dispensary I visit about once a week. We hit it off really well. Despite trying to just keep it casual sex, and that only, I ended up developing some feelings for her. She confessed the same to me. I even introduced her to my teenaged daughter, for fucks sake.
I ran into her this evening at a gas station, with another guy, who turns out to be her husband. They’ve been married five years, and have two children together, ages 4 and 2. Finding out they have kids just made me feel disgusting.
So, I told him. He didnt believe me until I described a tattoo in a somewhat intimate place on her body. I had no fucking clue she was married. I think I ruined someone’s marriage. Or at least took part in ruining one.
I feel guilty. I am sorry for what I participated in. Am I a bad person?
I think you're fine. What you did is always the risk you run when you're not open and honest with your partner. Making a point to never lie or hold back has made my relationships much better.
