<human>: Can you succinctly summarize the text in 1-3 sentences?

I [19m] met a girl [19f] last year at university. I took a liking to her pretty fast, but she had a long distance bf and I was talking to someone else at the time. So I didn't think much of her. We had one class that first semester, then the next semester didn't have one class together and only randomly bumped into each other on campus. At this point I wasn't pursuing her or anything.

Fast forward to this year (fall semester) and once again we have a class together. Turns out we have the exact same major. But once again she has a bf (at our same school now) and I actually have a kinda gf (long distance, complicated). So once again I didn't really have interest, just wanted to be friends.

We became pretty good friends and now this semester we have four classes together. Now we are both single (me in November, her fairly recently in January). I still haven't made a move or anything, but I been bumping up the flirting. I make her laugh a lot, and she can get flirty, but I just can't tell if she's interested or not.

Is it worth even asking her out? We've known each other over a year now and we've never hung out once outside of class besides to study.

So am I too deep in the friend zone to make a move? Is it even worth it? I wouldn't really care if she rejected me, but everyone knows the awkwardness that could come from that. Plus we'll probably have a lot of classes together the next two years here.
<bot>: Known a girl for over a year, both in relationships until now, too deep in friendzone to make a move?
