there's a qt at my workplace but it turns out she has a boyfriend (she's 19 and I just turned 21)

I'm ok looking and fit, I think I could win her but
1) I'd never start a relationship with a non-virgin (as I'm virgin myself)
2) If she leaves the guy for me there's a high prob she'll leave me too for someone else
3) I respect the guy even though I don't know him, I'd probably kill myself if this happened to me

wot do
