these situations confuse the shit out of me..

[boytwenty2]

So I just started my first year at community college. The other day I noticed this guy in my english class and i just thought "he's pretty cute" and aside from a couple sideways glances at him, I didn't really think much of it, cuz that's pretty much the way it goes with me and cute guys; I just sort of figure they're probably straight and they'll never want me lol and although I'll try to make them notice me, I'm not going to sweat it or expect anything. nbd.
Anyways as I was leaving class and walking to my car, the guy was walking the same direction as me so I just kinda quickened my pace so I could walk past him nonchalantly. I walk kinda fast anyways so this was just me doing my typical no-big-deal-cute-guy-walk-by, not thinking anything would happen.
All the sudden I hear someone go "hey, you" and I look over and it was him, and he's looking at me. I was really thrown off at first but i just go "ya?" probably looking really confused. and he was like "don't i know you from the cobalt?"
by this point we had somehow gradually gotten closer together as we were walking, and the conversation went like this.
me: "uh i don't think so... the cobalt?
Him: "the cobalt cafe"
m: what is that?
h: it's this really shitty venue.
m: hmm i think i've heard of that actually.. but i don't think i've ever been there.
(then i asked him where it was and stuff)
m: ya i think i know what you're talking about but i've never been there.
h: oh.. i must be thinking of someone else then.
m: maybe my brother? he's probably played there before.
-when i told him my brother's name tho he didn't recognize it and my brother is someone you would probably remember if you met him and tbh my brother and i don't look that much alike.
-then i asked him his name and he told me and he was like "aren't you in my english class?"
m: ya i'm *-----
-at this point i started to question whether this was like flirting or whether this guy was interested in me and we were still walking together so i decided to keep the conversation going.
m: so you've played at the cobalt? you're in a band?
h: ya!
~bla bla bla~

then he started asking me about the classes i was taking and stuff he was like "do you take a lot of classes here?" and we just talked about that briefly. i think at one point he asked me something like "what are you doing now?" or "do you have another class now" idk i can't remember exactly but i remembering answering that i was just going to my car. at this point we had to go separate ways, so we said goodbye, etc.
so here's my question: was this guy trying to talk to me cuz he was interested in me? it was a very brief conversation, and obviously kinda boring and super casual, with just the slightest bit of awkwardness, but i wouldn't really expect it to be any different considering we literally just met and i think we were both a little caught off guard. i felt like i was getting flirting vibes, maybe just because a guy has pretty much NEVER done anything like that to me before plus that whole "don't i know you?" thing just seems so cliche... but idk, maybe he really did just think i was someone. but he kept looking at me with this mix of confusion and intrigue on his face, at least that's what it looked like to me. but maybe he just thought i was someone and didn't expect me to continue talking to him once we realized i wasn't that person?? but he continued talking to me too and asking me questions. so idk. he was also definately outta my league tbh and he didn't even seem gay at all... ugh. point is...
IDFK. how do you tell when i guy is flirting with you? i feel like it's so much more confusing when you're gay because you don't know if the guy is gay or not.. like wtf lol.
so anybody with experience or insight, that'd be awesome. thanks!

and ps sorry if this post oozes with insecurity and desperation or if i sound really fucking pathetic, which i probably do, but i'm just not experienced or self-assured enough to really know what to think of these situations because i rarely get approached by guys so i just need a 2nd opinion. thanks.
