I am really shy and I can't even talk to him or look at him without giggling. I want to know how to ask him out or act around him. I need help. I want helpful answers not stuff saying I'm too young to be involved with guys and crap like that.

Sorry you are no "immature" to be dating at this point, you yourself said you can not even look at him without giggle,

So you mature, learn to talk to boys, learn to become friends and learn how to act around them.

Unless you can just treat him like anyone else, you are not ready to date yet.

It IS being helpful to explain to you that you are too young and immature to be asking boys out. Nor is it "crap" to give that advice.

Let me put it this way. Talk to your parents about it. If they feel you are old enough to data then they will help you learn how to act around boys.

All right so My advice Is.. If you like the guy tell him how you really feel If your that shy you can tell him over Facebook twitter bbm myspace texting Anything like that! Im in the same position as you. But what I do is I stay in touch with him via Facebook and bbm. Maybe when you see him give him a little smile or something Anything to give him a hint that you like him!for all you know he might like you back! But if you don't act soon He might think you don't like him because he's been waiting for soooooooo long for you to ask him out!! This is just my idea Anyway.
Smile,Say hi,Wink! or ask him what's up. Anything You never know It might change bfore you know it.

Im in the same position as you.

Are you also 13 and what do your parents think about your relationship?

I am in the same position and I give up now I am just going to go for it and try not to laugh I am going to do it in the afternoon so I don't have to face him for the rest of the day if he says no and just giving you some advice don't do it over face book or anything like that cause all the times I have done that it never works out so I think you should just go for it. :)

The easiest way to solve all this when you are 13 is simple: you go out in groups.
'My girlfriends and I are going to kick a soccer ball around Saturday afternoon around 2. If you want to join us, we could use more people. Bring anyone you want.' Don't even wait for a yes or no.
Or go to the mall or listen to music or whatever you are into on a spring day.

Save the datey-dates for when you really have a good idea that you might BOTH like each other. It takes time to find out and it's better than just walking up to him and blurting out 'will you go out with me.'
When I was 13, 52 years ago, we used friends to find out if someone liked us that extra bit. I don't see that too much has changed other than more girls are asking guys out than they did back then. But it's still all a complicated and agonizing process, LOL.
