I agree with everyone, and if just flat out telling him doesn't work, get mean about it. I know it sounds horrible ( I hate being mean) but its the only way some guys get the hint.

I had this issue a few times when I was in language school (that's what happens when you're in a male dominated area, lol).

Never been good at it, I always make thigs worse. lol. 

Im too nice, I need to be more blunt and say "I don't like you like that" or something

Oh my goodness, those kinds of guys (the kind that don't listen no matter what) are trouble!! They're SO stubborn! Don't get in a relationship with them! If you have to let them down, for some reason, you usually have to completely - and I do mean completely - ignore them.

I know how hard it is to tell them that you don't feel the same towards them. But it would be better for them to know than to get their hopes up for nothing.

I'm to the point with this one guy, where I have been mean, rude, nice, blunt, straight forward and he still doesn't take the hint. I am looking for a girlfriend, and I know after my class ends I will never see him again, so I'm tempted to tell him I have a girlfriend, or talk about this girl I'm interested in, in order to make him understand I do not want to be with him.

Its harder when that guy is a friend of yours. You know, a simple "I like you" can ruin a friendship because after he admitted his feelings to you. You'll totally feel awkward about it.

It really is harder when it´s a friend of yours.....this happened to me about two years ago......he confessed....I had had feelings for him before, but gave them up when he started dating my friend.....about a year after they broke up, he confessed to me. It was very sudden and startling for me. I considered him my only real guy friend (and he apparently read too much into that).I had to turn him down ( I tried to be as nice as possible, and he got the message), but it was so incredibly awkward......we actually haven´t started speaking somewhat normally until a few months ago, and it´s still a long way from how we used to talk to each other almost every weekend.

I know that people are always saying that one of the worst things you can say is "Let´s still be friends", but it worked for me. I told him that I still wanted to be his friend because I valued him a lot, also that I understood how he might not want to keep our friendship after this...and told him that I´d be waiting to reinitiate it whenever he felt ready to talk to me again. It  somewhat worked; he contacted me after 6 or so months, and we´re starting our friendship again.  But gah, love really complicates things. We´ll never be the same.

I've had it happen more times than I'd like to admit. I'm a natural flirt, something that I have to reel in, since it tends to give guys the wrong impression.

As others have said, blunt is best. You don't have to be rude about it, but simply say "I am not interested in you that way" or even "I don't want to ruin our friendship". The guy may be hurt, don't get me wrong, but there is no real easy way around something like that.

I know this sounds evil but i have friend zoned 2 men in my life and they both followed me around for 4 years @.@ Crazy huh?

I think the best way is to be honest! DO NOT SUGAR COAT IT it makes them linger but don't be a total *beep* about it either
