1 year 6 months I have loved this boy.. I'm still in secondary school and he has a girlfriend but I'm not sure he even likes me my best friend is bestfriends with him and she says he does but obviously not in that way but I'm sooo in love with him please help!;)

Well, if he already has a girlfriend and is happy with her, then it is going to be very difficult to get him even slightly interested in you romantically. He may just be one of those that gets away. It's hard to deal with, but sometimes that's just the way it is.

Just keep an eye on him here and there and see if he becomes available, then jump at the opportunity. If he's worth the wait, then you have to wait.

But keep your other eye on other guys, don't focus too terribly hard on this particular guy, there are others out there.

Bide your time. If it's meant to be it will be. But I think you have to prepare for some disapointment. He might really love the other girl just as much as you believe you love him.

Why would you be "so in love" with someone that already has a girlfriend? Find someone that is single and available to get involve with and hopefully build something with because this is a lost cause.

Your not in love your infatuated.

This guy is not available. To begin with...

He also 'obviously doesn't like you like that' according to his best friend.

It's time to get over it and move on to someone who

a) is available and b) likes you!
