3 months ago I dated a girl. We kissed on first date. 2nd date was a nightmare, I think she was seeing another guy in fairness. She ended up walking out.

So I blocked her out of my life.

i never got back in touch once. Throughout the 3 months I caught her looking a few times. And again in fairness I was looking to if I caught her. I've been much more proactive, and have been talking to much more girls, she has seen me talking to a few. My friends once shouted my name, when I wasn't there, she looked up at the group.

so yesterday she gets back in touch, just a a simple messaging asking how I was and how college was going. It was the last day of term, so I guess this has something to do with it.

So what should I do?
