What would you do?

Okay, So theres this guy, That I really like.. and I had my best friend tell him I like him, and he didn't beleave her he kept on saying nonononon she doesnt. And I don't want to ask him out, cause I'm to scared he'll say, no and it'll ruin our...

friendship. Everyone sais, "ask him out, He won't say no." but his best friend sais not to ask him out on myspace, cause he doen't like that. Don't ask him out around his friends, or he'll say no. So, I would have to get im by hmself, and I don't know how to do that. And I really like him.. I've like him fo 3 years. We talk a lot. and I really don't wnna ruin our friendship, by asking him out. him saying no.. and then everything going from there. Like I had a friend of mine.. Ask him out for me at lunch.. and he said no he was infront of all his friends..but I don't even thought I liked him at that time though, Like we talk a lot and people are like "You like Him!!" and he likes sticks up for me and said something like "Shut up, you like Alex" (alex is a really really obesie kid in my grade that everyone makes fun of) and I get happy. But I don't want to make the wrong move.. and make a mistake I don't know what to do? Any advice out there.. Please help!!!

First off just because everyone makes fun of an obese kid in your grade, doesn't mean that you should too, that's terrible.
Also, if you like him, get up the guys to ask him out. Take the chance now while you have it, before he finds someone else. You never know what will happen if you dont just go for it. What's the worst that could happen.
