<human>: Can you summarize the given text in a few sentences?

So, last night I went on my first ever date with a girl I met on a dating website that I've been talking to for the past week and a half, and it's amazing how much we share in interests as well as how lovely she is.
For the time I've known her we've been exchanging these massive emails and been really enjoying talking to each other, at least that's the impression that I get.

Then last night, we went on our first date, and it was great, dinner, followed by chilling at her flat talking while listening to music, then meeting a couple of her friends at a bar where she had a few drinks (I didn't as I was driving), and then back to her place for more chat, music and a cuddle.

But the thing is, while she had a few drinks, she started opening up a lot about how she only recently got out of a long relationship (broke up 2 months ago, from a 4 year relationship) and she ended up deciding while cuddling to tell me that she wasn't ready for a relationship. I got the feeling she was really enjoying my company though, and it could possibly go somewhere in future, I'm definitely interested.

So, my question is, how much is the not ready a warning sign to step back, I don't want to push her into something, I'm not sure how much time she'd need, it always differs from person to person. I just don't really know how to proceed with this situation.
<bot>: First date was amazing, but she isn't ready for a relationship so soon after her last, and she said this, what does this mean and what do?
