Just replace her. Everyone is replaceble. Literally everyone. Once you come to that realisation, it becomes much more easy.
All the people you knew from when you where small? Replaced by new ones.
The guys you knew during school? Replaced.
Connections you made in University? Gone, replaced with new ones.
What makes this piece of flesh so special to you? You probably dont even talk to her. You dont have a crush on her, you have a crush on your fictional, idealized version of her that most likely doesnt even exist.
You soon find a new one to replace her with.
