Girl has bf already but seems interested. Pursue anyway?

Just....don't, man. Go try to meet some other women. I had a somewhat similar situation happen to me last November when I was about to graduate. Disclaimer, sob story below:

I was pretty lonely at the time since the few 'friends'(more like acquaintances) I had had in college had left, and I met this girl who I hung out with for a bit and had a blast with. It really seemed like she was attracted to me. I'm not a good judge of this shit so she might not have been but she certainly made it seem like that in my eyes. She'd say things like 'I really like nice guys/not bad boys'(whatever that means but she was implying that I was a 'nice guy'), 'I really like guys of [my] race, [my] culture(different from my race)' but problem was she had a boyfriend who was out of state. Whatever I tried to ignore it, I was just really happy to have someone cool to hang out with. I thought, 'I'm not going to try anything with her, it's great that I'm having fun right now and have a friend'. Sure, I'm attracted to her and would go out with her, but so what?, I thought, I'm not even sure she likes me, she has a boyfriend after all, doesn't mean I can't hang out with her. I come back the next semester after winter break to the same city where my college is to work and I start asking her to hang out with me, you know, thinking we're friends and shit. She meets with me a couple of times and seems like she's losing interest in me, tbf I kind of start getting nervous around her out of fear that she might not want to be friends anymore (got super drunk at a party just before winter break and blacked out in front of her friends and she called a cab for me. Yeah.). And maybe(maybe not) as a result of that, she starts flaking more and more. She even mentioned once, jokingly, that I was needy. At this point, I'm getting kind of mindfucked since I'm not really experienced with people in general after so many years of being by myself in college. I didn't text her that much (I think), ask her to hang every weekend or every other and have her reject me most of the time (like five before I just stopped asking). I'm coming across as 'needy' to the only person I know and trust in this fucking town. That doesn't sound like friendship, that actually sounds like someone who's attracted to me or at least was. But at the same time, she seems pretty extroverted and has lots of dude friends, so maybe I am needy since I'm so fucking lonely? But if she sees me as a friend, why did she stop initiating things when I asked her to hang out and she'd reject me? Was she just attracted to me and didn't see me as a friend at all and lost it when I started acting needy?

Now, I don't think I'm friends with her anylonger, let alone a romantic partner, and I'm back to having jack shit for friends. I'm pretty much in a state of 'what the fuck just happened'. I don't know whether to be angry with her for deceiving me into thinking we were friends when she had a boyfriend and she actually might have been attracted to me but lost it because I wanted to hang out with her all the time because I had nobody. Or whether to be dissappointed in myself for losing a good friendship because I let my inner attraction taint it and get it mixed up with my desire to have friends. There really could be a variety of different reasons, and i'm just going to try to not blame anyone for it.

Sorry about that OP, just kind of wanted to rant a bit on my obsession. I guess what I'm trying to say is, try not to put any emotional investment into her and pursue some other girls. If she's into you, she'll come after you. If she's not, at least you have a good 'girl' friend to hang out with occasionally.

Re-reading my almost dweeb like story, I seem hopelessly out of place on this sub lmao.
