don't let a guy make you feel so depressed and angry, he sounds like an idiot to me...anyway, who gives a crap about boys when you have a whole life to live...enjoy it...and DON'T let him get you down!!!!!!!
Boys are dumb sometimes. Okay, that's an obvious statement, but they really can be. I was going through the same deal over the past few months. I don't know if it will help, but if you're questioning how he feels about you, and when it really gets you down, try listening to "She's Gonna Hurt Somebody" by Chuck Wicks. At least check out the lyrics. I listened to it over and over. It sort of changed my perspective on things and I didn't feel so down about myself or the situation.
Also, try talking to him about it, if you haven't already. Just explain what you're feeling (like how you said in here.. that you feel as if he doesn't want to talk to you, or that he might be bored with you), and ask him to explain his side of the story. Maybe he's just stressed?
Give it a shot. :) The best of luck, and I hope it turns out great for you!
