I have this same issue with a guy. I've technically known him for three years, cause my sister always talked about him to me and his sister apparently talked about me to him, our sisters are best friends, but I only talk to him in two of the classes I have with him, and don't really text him. There is a Sadie Hawkins winter formal coming up, and my sister grabbed both of us after school one day and was like "You should go with him!" He was like "Haha if no one else asks me" I was like "wtf" then he said haha jk and walked away, he likes to screw with me idk why. I asked him who he was going with to the dance and he said, "I don't know if the girl I want to go with is even going, so I'm going with my friend" I've been asking him who for a long time and he refuses to tell me, It's so awkward.. I don't know if we are even friends or not he always says I have such stupid games on my IPad (for school) and that I need to stop. He also always tells me he likes my sister better, and normally ignores me in the halls. This is such a rant sorry.
Thanks dude, you help me a lot
