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

Hi all! 
I met a girl in a small English class last year (also my LAST year at Uni), and we hit it off well, started talking on FB and texting, then getting to the point where we're snapchatting each other for days at a time just making silly faces. And while it took a while (there were a few months where communication was low), we went out for drinks a few weeks ago and talked for a few hours, only stopping before both of us had other things that day to do. We both admitted we had a great time, and that we should do it again.

Here's the point where I get hooked up when I like someone- I'm not always sure how I should go asking them out, even if I think she may say yes. The problem is that when I get this close, I start reevaluating whether or not what she's doing indicates that she likes me, and I start second guessing myself. And for all the positive things I just listed, I'm still the one who usually has to initiate our conversations, and while I wouldn't say she's been dodgy about meeting up a second time, earlier this week when I pushed about it she said she'd get back to me the next day about her schedule. We then talked more the day after, but she never brought it up.

When this kind of thing happens, I tend to psych myself out a bit, and by the time I usually muster the will to ask her out, I either botch it, or sometimes enough time has passed and they've lost interest. Can someone with an outside opinion give me their general idea on where we might be right now, given the meager summary I've tried to provide?
<bot>: Met a girl, started chatting her up and getting close, but now a mixture of self doubt/changing conversation patterns are making me wonder if I still have a shot
