Okay... sorry for being vulgar, but I need to illustrate a point here.
One time I was at a bar walking. I hear someone say my name. It's this girl I knew and her 2 friends. They are all hot. Super hot. One of the friends is this girl I saw at a pool party and was like in love with for that day. So I start talking to her. Come to find out she's cousins with one of my friends and all this stuff. She stops me and says "Emily wants to fuck you." I immediately think "I kinda knew that.. " then continue the conversation. About 30 minutes later they leave the bar in an Uber... Emily ended up deleting me on Snapchat like year later and we are no longer friends.
Point is... If you straight up tell the guy you like him, it probably won't do much for you. He probably already knows that. What you need to do is just tell him to go do something with you. Be like "hey I'm going see this movie later. You're coming." He might be all like "but I got this thing....". Tell him "yeaaah.. you're still coming"
