Well I tend to think somebody might find out we like eachother and also I worry if I say something stupid. Plus she's always hanging with her friends and I don't want to look like an idiot in front of her. I can talk to every other girl just fine but I like act like she isn't there which makes me sad :(
Why would you be embarrassed to talk to a girl you like and a girl that likes you? The only people who are going to be judgmental are either jealous or just playing around with you.
Plus, if you have share feelings with someone about each other, embrace it. Trust me, if she ends up ditching you before you get to do anything, you'll be hurt.
