She treated me like shit so I left her a year ago. I still kinda miss her & I still haven't felt anything close to what I felt about her towards anyone else. Did I fuck up?
No, I was the same way, I pined over a girl who basically shit on me (she was my first gf at age 21). And I was crazy for her for a long while, it wasn't worth it. She was shit, just focus on being a good man.
