I started talking to a girl I really like. Later on I found out that a guy from my class also likes her but doesn't have the guts to start a more personal conversation with her.
As soon as I start talking to her he makes fun of me, loud enough so everyone can hear it (especially this girl and my other friends).
He's trying to make others make fun of me aswell. I don't know if he wants to embarrass me or if he's trying to dissuade me from talking to her so that he gets a chance to hit on her. Either way, I don't think I should stop because he's acting like an annoying little kid (we're both 17 so I think he's old enough to realize that what he is doing is completely stupid).
Should I ignore him and keep doing what I want? Any advice would be appreciated.
