I need guidance...

Saige

I'm a senior and there is a guy in college that used to go to my school that I have always been attracted to. When he was in high school he was kinda a player and douche but he's gone through a real mature phase and has really grown into a wholesome, positive, sweet, caring christian. We were never close in school and haven't talked in a while but I haven't been able to get him off my mind. I recently followed him on insta and snap and he's followed me back and has liked every one of my pictures since (which I'm sure is nothing just the girl in me). Again we haven't really talked but I am super attracted to him on both a physical and mental level.

what should I do??
