Many months ago I was in a long distance relationship. I had reason to suspect my girlfriend was cheating on me. Let's call her Jane and let's call the "mistress" John. (What do they call a male mistress?) Far as I was aware Jane and John were constantly spending time with each other. Jane's sister even suspected it when she saw them being a little too friendly with each other. But at that time it still wasn't enough to be 100% sure. Months later John dies for an unrelated reason. Jane was heavily grief stricken. But that reason can't confirm crap. John left everything to her. Okay getting more suspicious. She gave me his car since he drove a 2012 Honda Civic Lx Manual. She doesn't know how to drive a manual. I do. We soon broke up for unrelated reasons. (I'm not lying.) I'm cleaning out this car, getting ready to sell it, because I have a thing against foreign automakers. (I come from a family of Ford Factory Workers who worked in the Dearborn, MI plant. It's how I was brought up.) I find a burner phone in the glove box. It wasn't pin protected so I snooped in it. It was Jane's. She used it to text John all kinda os things. One of them was arranging a hookup. Then one dated the next day talking about how good the sex was. Then one saying that she's going to give him the phone and he was supposed to destroy it. John never did. I'm hurt. I can't believe this is true. Why would she do this? How does someone recover from this kind of hit below the belt? How should I confront her?
