Ok, earlier on in the school year I sent a text message to this mate with some gay things in it... now he thinks I'm gay (Which I'm not). He told a couple of his best mates, now he won't talk to me and they sometimes call me gay and things... please help..

What Can I Do?

Well, the things you sent in the text, were they just jokes or what?

Tell them you are NOT gay. Don't be joking or anything when you say this. Be assertive and show them you are serious. Just set them straight.

Hope that will help a little...

What did you say in these text messages?

get him by himself and talk to him about it. Tell him you were just being stupid.. if he doesn't understand just say 'I just thought id tell you', walk away and if they tease you about it again ignore them.
like I always say, if their true friends they'll believe and forgive you

Just tell him to not take things too seriously, and if he's going to do that to you then he's clearly not a very good mate?
