A guy that goes to my school keeps asking me out and I keep saying no. And my boyfriend keeps daring him to ask me out. I keep saying no because: A) he has a ponytail B) he never does his homework C) he teases my friends.
Why does he do those things

I'd be more concerned about a boyfriend who keeps telling some guy to ask me out, especially after I have repeatedly told him no. What is my boyfriend trying to prove?
