<human>: Can you give me a shortened version of the text?

I met a girl through mutual friends years ago and tried to ask her out several times. She rejected me politely and I ended up giving up so it wouldn't be weird. 

Fast forward to the present day, and I still see her around occasionally since we hang around some of the same people. I treat her like anybody else, but she gives me flirtatious smiles all the time. It's pretty confusing. It makes me feel like I still have a shot and it makes me want to go for it one last time. 

I just don't want to be the guy who can't give it up. If she liked me I feel like she could have let me know by now. She knows I'm into her, or at least that I was. On the other hand, I'm about to graduate. I'll never see her or most of my college friends again. Part of me doesn't give a shit if I come off as a desperate, creepy douche who can't give up the ghost to everybody.
<bot>: Should I give it one last shot? Or am I embarrassing myself? Or even if I am embarrassing myself, should I just not give a shit and do it anyway?
