Signals?

Hey y'all! So last summer I went on a date with this guy who I really really liked (and I still do) but then we both left town for the holidays and we didn't keep in touch so I thought that was it.

Since September he has occasionally replied to a few of my IG stories, and about 3 weeks ago he invited me at his place through one of his classmates (who is my very good friend) because they were having a reunion I suppose, but I had a concert that night, so I couldn't go...

What do you think he's doing?
