I, too,learned by accident.
I invited my WH to meet me for dinner after work, telling him I wanted to talk to him about something important. See, he had been acting suspiciously,so I had snuck out to his truck in the dead of night a couple evenings earlier. I dug around in the truck, looking for a clue to his strange behavior. And I found what he was hiding, I thought. There was a vape under the drivers seat. He supposedly didn't smoke, so I was going to playfully bust him at dinner...
So there we are, sitting side by side in the booth having dinner, and I brought it up:
"I know what you've been doing, what you have hidden, so why don't you just tell me?" I was smiling up at him, my arm wrapped around his, leaning against him & feeling so deeply in love with this strong, hard-working man who had been sneaking around to vape. He shifted uncomfortably, fidgeting, and all in one breath he said, "Ok, before-work-in-the-mornings-I've-been-going-across-the-street-to-the-park-to-have-AA-meetings-wi th-Ryan."
What?!?? I sat back in the booth, letting go of his arm, laughing. Confused. It was like cutting open an envelope & expecting a letter to fall out, but a dancing purple hippo fell out instead. I was so. damned. confused. What was he talking about? Who? What???
So I choked out, "no, that is some sort of crazy lie. What is going on here??"
And then, my perfect world exploded. Baffled, I told him, "I know better. I'll give you a chance to be honest with me. One chance. I already know the truth, but it would mean a lot to me to hear it from you." Which was a lie--I knew nothing. All I knew was that he had a vape under the seat in his truck.
After some hemming & hawing, an interminable pause, he told me he and been seeing a woman at the park, and riding to & from work with her, and had been her BOYFRIEND/lover for the past 3 years of our short 4 year marriage.
And there I was, my enchiladas turning to ice as my still-beating heart was ripped from my chest. Jesus.
CHECK PLEASE!
Um, yeah ... I'll never go out to Mexican again.
