Would you keep in touch with someone you'd been on a few dates with?

So I met this girl a couple of months ago, we've been on 4 dates, kissed on the lips a couple of times and held hands also.

She's gone traveling in America for 5 weeks, and she comes back next week. Now since she's been away she's been messaging me every now and then over whatsapp and been keeping in touch.

Last friday I went away last week also. She told me she'd talk to me when she gets back home. I got really drunk on holiday and sent her a text saying that I was sorry for not keeping in touch as I the hotel hadn't had got wi-fi which was true. I didn't hear from her for the rest of the holiday.

When I got back I put up a facebook status about me getting back to London and about an hour later I got a message off of her!

Now my logic is that someone in her situation wouldn't keep in touch with someone unless they wanted to see someone (ie me) when they got back. I can't really see the point of her keeping in touch with somebody for the sake of being 'friends', in our situation anyway.

What do you guys think?
