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

I'll start with a bit of back story. So me and this girl went to High School together and were always quite flirty to the point were people were telling me I should stop for the sake of my current girlfriend at the time. We both went off to university and didn't talk until now 3 years on. During this time me and my ex girlfriend split up we'd been together for 5 years and broke up about 3/4 months ago. She also had a boyfriend at the time, but looking at her facebook that appears to be over too not sure for how long.

Anyway she started texting me a few days ago and she wants to meet up. I always had a bit of a thing for her so I thought why not plus it'd be nice to catch up.  I asked her where she'd like to go she suggested a few things and we settled on going to the zoo for the day. 

Now I'm not sure when she says catch up whether that means just 2 friends catching up or more of a date thing? I dunno whether it would be appropriate to make any sort of "move" like going to hold her hand or put my arm round her or something?

I was planning on playing it by ear but thought I'd ask here and see what you guys thought
<bot>: Old friend wants to meet up out of the blue? Is it ok to make a move? How should I do this?
