I have a male friend called *George*, basically, last year we became really close friends and would go out with each other all of the time and do anything for each other.. He also used to tell me that he loved me (as a friend). But recently, he became slightly mean in school. I think it's mainly because he's become friends with *Harry* who has a tendency to take the piss out of people. Anyway, though he used to a bit, he started embarrassing me all of the time and picking out tiny things that aren't even worth mentioning and enlarging them loads just to make people laugh (which they don't).. At first I thought he didn't realise what he was doing so I tried to tell him but unexpectedly got replies saying stuff like 'yeah but it's funny'.. I then tried to tell him that it may be funny to him but it isn't to me but he just didn't seem to show any sign of morality. Finally, I got sick of it and when we were cycling home from school, I brought it up again but this time really showed how annoyed I was and when he didn't see my side at all I just cycled off. I would never usually do a thing like that and so it managed to actually portray how annoyed I was, then he cycled after me and started being really reasonable and saying sorry. We negotiated in a way what he'd stop doing and after that he's been slightly better in terms of taking the piss but since then, we have really seemed to drift apart even though we still see each other just as much. He doesn't seem like he loves me in the same brotherly way he used to and I really miss our old friendship.. How can I get things back to how they used to be? We used to confide in each other, and hug each other good bye... I promise he is worth it

Okey I have a best friend who's a guy and we are closs but he is mean to me and I no he's joking but it does still hurt so I no what you mean, I just when he does something that hurts me I pretend to get really upset because he hates seeing me upset then he says sorry, but I can't do that forever, and its good that you said something to him to tell him how you feel.if he doesn't stop you can keep telling him that you hate him doing that to you,and get angry at him if he keeps doing it so he can see you don't like it.
Sorry can't think what else to do, hope this helps :)

For one, a lot like what you did, you have to be clear when and why he's being a ****. Us guys like to beat other people down for our own self ego. It makes us feel better about ourselves. One thing that I've learned though is that not all people find it funny and girls especially don't find it funny. Also, it can be very hurtful. So be CLEAR as day when he's bothering you.
The second thing I have for you is how to rebuild your friendship. I recently just starting repairing a friendship. What I found to be helpful is complete honesty and to blunt one another. I flat out told the person why I was pissed off. I told them how I was feeling and exactly what was bothering me. There was little vagueness. It helped a lot and I couldn't believe how much better I felt. The second thing I recommend is to repair your friendship based off the values it was founded on. For example, trust is the biggest thing to me, along with respect to others (and each other), and caring for one another. I worked on these a lot with my friend and now I really feel that we are starting to become close again.
I hope this helps a little!
