I'll keep it short and sweet. I'm obsessed with a girl from my college class. We're decent friends at best, never had sex with her, never went out, never did anything sexual at all with her. She has a serious boyfriend and she also has a guy friend she spends alot of time with. I find myself so jealous of this guy friend it's driving me insane. I've even considered dropping classes or just going no contact on her to help things.

Is this even remotely normal? Why would I be so obsessed with a girl that I'm not even that close with... is that pathetic?
