<human>: Can you provide a brief rundown of the text in within 3 sentences?

This is the first guy I've met in my major who I really like for both looks and personality. Back when I knew nothing about him, I'd catch myself gazing in his direction during class. I thought he'd be nothing but eye candy whom I'd never get to know, but slowly we started talking and I found out we have similar viewpoints and interests. I have mild social anxiety and he's one of the few people I click well with in conversation. 

Out of curiosity I looked him up on Facebook once and saw he's into women. I don't know if I'm still hanging around this guy out of delusion, or maybe it just makes me really happy to hang out with someone I find attractive but also click well with. 

He doesn't know I'm gay and I've made no moves for fear of damaging our friendship. But today I came close to telling him I like him. I'm hoping there's a way to find out if he could be into me at all (I know his profile says he's straight but I stupidly need to know for sure). Or I don't know if I should start flirting. Or if I should flat out tell him how I feel. I'm at a loss here.
<bot>: I have a crush whose profile says he's straight but I want to know if I can find out for sure or if I should make my interest in him known.
