A break goes better for my ex [FM] than I [M]

This is a bit different than the stories I see on here. Kind of from a voyeur perspective. Potentially sort of like cheating but I don’t consider it full cheating.

My ex fiancée Juliana and I met freshman year of college. She was adorable – and we were each other’s first relationship. Both of us were so inexperienced and awkward. She was super hot and didn’t know it – Russian and cute. We fumbled through sex and were having a lot of fun even though the sex was very mediocre in retrospect. I had trouble lasting more than 15 seconds and she was super shy and wanted one position with the lights off. I was elated and couldn’t get enough of her even though I was probably very selfish in bed. Tbh I rarely saw her naked – she was so shy.

Sophomore year we lived together in an attic off campus. We ended up fighting a bit more and she became jealous of a friend I had met in class. It was partly my fault as I liked the attention this new girl was giving me. Juliana took my phone and read the messages and flipped out on me. There wasn’t anything damning but she was really upset. I decided I wanted a break. We were both poor so we stayed in the same apartment – we even shared a bed but never had sex. It was very awkward.
