<human>: Can you provide a brief overview of the text?

Hey guys, I've not had a lot of experience with relationships, and have only recently had the confidence/realisation that I need to be direct and ask girls out if I'm interested in them. Anyway, I asked out a girl last week, and we went on a date recently. It seemed to go OK, although we didn't kiss or anything. 

The problem is, any time I've messaged her on Facebook, she always takes ages to see the message + respond, or sometimes doesn't see the message at all. I messaged her after the date we went on, and she still hasn't "seen" the message even if she's done other stuff on Facebook since then. Any time she has replied to my messages though, she always sounds quite positive, and obviously she said yes to the date in the first place (and I did use the words "go on a date" when i asked her out so she knows what it was). 

So my question is, do you guys think she's trying to send me a hint that she doesn't want this to go further? Maybe she only said yes out of politeness, as wouldn't she be more interested in the conversation/replying if she was genuinely interested? Or is she just trying to "play it cool" and not be too eager to respond, in which case should I try and ask her out again?

Thanks in advance you guys!
<bot>: Went on a date with a girl, but not sure if she's interested as doesn't seem particularly bothered about replying to my messages.
