Shadaria

Me n this guy we went to school together, I haven't saw him in years. A couple of week ago he hit me up on Snapchat to meet so we did . The first time we he was kinda shy but i want to get to know him more, a couple of weeks after I was talking inappropriate too him being bored after that, He wants to meet right away lol after every week but I'm started to like him but he still wouldn't open up to me. what's is that?
