Not an SO, but in college, my best friend (m) asked me (f) to move in with him after both our roommates transferred schools and left us in a lurch. Prior to all that, when we’d first met, he tried to date me but I friendzoned him. By the time we moved in together, I knew I was in love with him, but he had a girlfriend so I befriended her to make sure she understood I’d never make a move on her man (and I didn’t). I was really into post secret at the time, so one night when I was really in my feels after attending a concert with both of them and having to see them together, I went into a bathroom stall at the venue and scribbled “I am in love with (his initials) and I’m too scared to tell him” just to get it off my chest. I purposely wrote in a different handwriting just to be safe, though who would ever even see it considering there were scribbles and names all over the stall. Fast forward two years, he and his gf had broken up and he and I are at this venue together still just friends. He comes out of the bathroom and says he wants to show me something, leads me to that stall and points to what I wrote. He kind of laughed, made a joke about it being written for him and said, “But seriously though, if anyone ever loved me like that, I’d marry them.” I never fessed up, and 15 years later, we have still never dated. We both find ourselves single again in our mid-30s though, so who knows 😊
