I would say 1 is the more likely reason. So to me, I'm like why even try because for me to go in there and try to ask her to hang out or on a date would just be another guy being interested in her like many others before me who have yet to succeed. To her i feel like it'll be like "ohh been there done that" kinda thing.

If she doesn't want you then find someone who does!

Just ask her. Maybe there's something about you that she thinks is cute... you don't know. Maybe she's only picky because the other guys were douche bags; maybe they were trying to get laid on those dates.
Let's not assume she's a Goody-two-shoes either, maybe she's already been sleeping around with these guys and she's just cool with that lifestyle. Fact is, you'll never know unless you just talk to her. Go.
