Same shit happened to me-found a love letter written in Spanish (had my friend from Guatemala translate it). I took pictures and put on iPad-then handed to her while we were looking at window curtains saying, “how about these?” I’ve never seen somebody get so uncomfortable in my life-was literally digging her nails into her skin, then began crying and saying “I made a mistake” - the next night she left in mid of night and I never saw her again. I tracked down her therapist to facilitate the legal divorce who told me she denies the entire thing. After having time to process it all, it came to me that every time we were in her parents house she would come on to me-and this was the only time she ever did that - made me think she mostly got off on the promiscuity rather than the actual transfer of love or feeling, which has later fed me validity in open relationships. I was nearly the exact same age u are now and that was ab 5 years ago - I’m so much better for it.
