I really like this guy and he usually doesn't say much when I see him. It surprised me when we matched on tinder. I waited a few days before messaging him because I wanted to see if he would message me. I thought that maybe he could've accidentally swiped on me. Anyways, I messaged him, and now its been 2 days and he hasn't messaged me back. Does that mean he's not interested or could he be shy? Should I try messaging him again or would that come off as desperate?
