I Need to Vent

A while ago, I accidentally swiped right on a girl I went to school with last year on Tinder. I didn't mean to, not because I dislike her or anything, just we didn't talk much at all and I was sort of a fumbling mess back then.

Well, today we matched. I don't know why she swiped right (maybe she also did it by accident somehow? Maybe she wanted to see if I had swiped right? Maybe she didn't recognize me?) And it's making me really uneasy.

I feel like I should send her a message, but I REALLY don't want to. I want to ignore it, but that's so awkward...
