Short Info: Im a 20 year old male and i never had a girlfriend. Had sex with three different girls and made out with a bunch but it never got serious. But the second girl i had sex with, sticks into my mind until today.

The Problem: I simply cant forget her. We dated a year ago and it didnt work out. this jannuary we talked again and agreed on a fwb sort of thing. Had sex 4 times and got closer. (she even met my parents and friends!) From one day to another she lost interest and moved on. (i know its my fault because i started acting needy rip).

Now the actual problem is that i just can't move on for 100%. I started lifting and made huge progress which i am very proud of but i still think of her nearly every day. She wasn't perfect, i kind of idealized her for sure, but some traits were the ones that i looked for in a girl, but i can't manage to find them in another girl. I'm really looking for advice on how to finally forget that fuckin oneitis and move on.
