Have you ever had a relationship that you look back on and think 'wtf??'?

For 6 years (11th grade through senior year of college) I had a very good guy friend that I spent a lot of time with. The first three years he was my confidant, someone I could talk to without judgement. We would play video games, walk around parks and talk, go to the mall...normal friend stuff. When my ex and I split up shortly after the birth of my daughter...our relationship changed. While on breaks from college, he'd come over and stay the night. We never had sex or anything like that but he'd lay in bed, hold me, watch movies and then in the morning he's leave. We spent most of our free time together. After a year of that, one night, out of nowhere he started kissing me. We made our full force and it was hot but still nothing physical beyond that. So, we kept doing the overnight, cuddles, movies and making out. Then we started listening to romantic music, talked and a little bit of fondling. After two years of this, one night he ended up fingering be. I wanted sex, he said no. We hung out a few more months...same old thing, talking, more vies, cuddling, kissing and then I went away for a few weeks and met a new guy. When I came back, I asked him to hang out and he said no because he had a girlfriend. To this day, I look back and think...wtf. We weren't dating, weren't having sex, but there was definitely something there beyond friendship.
