Haven't had many partners but God, as a 15 year old there was a girl who I had a huge crush on in the year above me. Got a mate to ask for me, she said yes and we went out for a bit (like a week!). But I was too much at that time. Writing her letters and passing them in the hallway, lol. She wasn't keen (or ever was) and dumped me. I died a bit that afternoon.
How many times have you dumped?
Edit: the crush was long though, like 6 months before
