How do I know if she likes me if she keeps giving out mixed signals?

Well here’s the thing. I met this girl at a dancing event, yeah, she’s a b-girl. I kinda liked her but didn’t approach her that day. Anyway, I somehow got to know her name and then connected with her on Facebook. She replied and reciprocated quite well. We got to know each other. Then there was this another event coming up and I asked her if she’d be coming to which she replied in the affirmative. I went on to talk to her that day but was nervous and only spoke to her after the event got over. I knew I’d have to introduce myself again as she’d not seen me before. But I to my surprise, when I went on to talk to her she recognized me ( ‘cause of the profile pictures on Facebook I guess). Anyway, so yeah, I was flabbergasted and didn’t say anything. Then she said that she’d seem me sitting over there all along and asked me why did I come so late to say hi. I was totally blown. After sometime, I left and said that it was nice talking to her and she was like say hi on time the next time you come! Then there was this another anniversary event of her crew and I was gonna be late due to some reason and the entries were limited, so I asked her if she could do something so that I’d be allowed to enter late, well I wrote a pretty long message. she then replied that it wouldn’t be a big deal, then further said that she’s sorry she couldn’t write an equally sweet and sincere message as she was kinda running around and all. I met her that day and when I was leaving she told me to give her a missed call in case something like this happens again in the future so that she could do something about it. I then gave her my number. I started texting her, initially she used to reply but then that usual no-replies thing started! I know it happens but it still freaking demotivates me. Now recently, I asked her what she’s up to she she told that they’d just performed at this place. I couldn’t miss this opportunity and then I replied, “well I figured’ cause you’re always performing someplace or the other. Speaking of which, do you ever get time to do anything else, like just go out or something?”. Then she was like haha, its difficult but not impossible. I then asked her to elaborate on that difficulty part and then I was gonna call her and ask her out on a date. But, no reply! I sent another text that I’d be coming to this place tomorrow as you guys practice over there, so better be there. Again, no reply! I’m sorry I didn’t want to end up writing a biography, but I wanted to give all the details so that I’d get exact answers! I really like this girl and wanna make things work!The part that confuses me is that she was the one who gave me her number without me asking for it. And the fact that she recognized me the first time we met. But again, the no-reply part kinda messes it all up again! PS : I haven’t called her yet
