M/19/college freshman

Situation is I hit up this chick over thanksgiving break who I used to have a thing for in HS but who always had a bf. She seemed pretty down to see one another again and I told her to hmu when she was free and never did (the break for her was only 4 days, not a ton of time). So I figured it was an L and moved on. Then She hit me up today and asked when I got back for Christmas break and then said she was sorry we couldn’t hang out over break.

Is it worth pursuing? I’m conflicted.
