I'm in second year and there's a boy in my class, who we are friends and I got his number a few days ago! I really like him but we have just been talking about normal stuff! He said to a girl, I was sound and I'm not really sure if he likes me. I don't want to say I like him if he doesn't feel the same and then it might ruin our friendship!

Depending on how known you've long him for, you could play it ways
a) if you haven't known him long just stay being friends for a while, get to know each other then when you think the time is right or
b) if you have known him a long time then just tell him, but be warned guys (inc teen boys) r well known to clam up and run away, if this happens give him time to think it through, away from his mates. As eventually he will come back and be ready to talk to you
Hope this helps

You should spend time with him and find out what he likes and if he is having any problems you should support him that can make a guy like you if your there for him and understand and take care of him like if he was ill and you took care of him yif he was upset you should give him a hug and make him laugh when you know he's about to cry xx :)

Doesn't matter. :'( he just asked out my best friend! :'(

Oh I am sooo sorry! :( But just remember what is meant to be will happen... if you really really like him then you can wait until their relationship is over... it sounds kind shady with your best friend but just see how there relationship goes
