This situation isn’t current goes back many years ago but to cut a long story short a lad I used to know said that when he was 15 - he had a friendship with a 10 year old girl he met on holiday. She even stayed occasionally at his house at that time! He tells me it was a totally non romantic in any way, a purely platonic friendship and knowing him I totally believe him - but AIBU to always have felt a bit eww!! about this? (even though definitely non romantic, and purely platonic) ?
