Ex texted me after running into me yesterday?

Went out to a party with a few friends; ex had texted me beforehand asking if I'd be going and that she "looks forward to seeing me again", and tried to start a text convo asking how my day has gone. I sent a short reply back saying "will see", and proceeded to go to the party. (Prior to this text, we hadn't talked in 3 months).

Fast forward to today: I get another text from her saying "hey, it was really good seeing you yesterday!!". Unsure why the sudden urge to try and text again, and how I should proceed in interactions w/ her.
