guy help!!

Kayla
Okay so this guy from my college slid into my dms and got my number and asked to hangout sometime. He's nice but he's really into drugs and I'm just against that kind of stuff. I don't want to hangout with him but idk how to get him to stop talking to me/asking me. I don't have a good reason 😬 I also see him all the time and have mutual friends so I sometimes am at his apartment. I don't want things to be awkward! Help!!
