How can I pretend I'm not bothered about him?

There is this boy who's called Nathan and he always takes the mick out of me its like one second he's nice and another he's so URGH and it does my head in! Ok I tell him I get in a stress when he calls me cause I remember when he was nice to me and he just laughed in my face and I said you know what I'm f***ing sick of it. I hate it . but he's bound to take the mick out of me so suggest some ways I can't act bothered about it??? and do you think he likes me cause I'm the only girl he takes the mick out of!!!

Ignore him! he is getting what he wants becos you are letting it show he gets under your skin! if you ignore him and act like he doesnt bother you at all it will scare him that he isnt getting a reaction out of you!

He might. You see, we males are stupid. we can really only use one side of our brain at a time, and if we want something, we can do some stupid things to try to get it. Some are just better. Tell him to stop it, if he does then yay, do a dance. but if not, just don't bother with him. ignore him. he may give up, but like I said, we're stupid. So he might not. if he promises to stop, only give him one chance. Best way to get through to him. Good luck, hope it works out
