My DS, an only child, and his so called best friend have been friends since they were babies. They've been right the way through primary school together, walked to and from school together and spent hours at one another's houses. A while ago they discovered Clash of Clans, best friend set up a clan, DS joined and they have been playing amicably together along with a group of their school friends. Enter a friend of a friend, a slightly older boy. Things start to change. Best friend 'kicks' DS from clan for no apparent reason and then goes off on a residential trip for a week leaving DS out in the cold. He returns and things seem to get back to normal. They continue to walk to and from school together and spent time at one another's houses. Then best friend decides to start 'clan hopping' and passes leadership to older boy. Things get too petty for me to go through but the latest development is that DS has again been kicked from clan having received a message in shouty capitals with asterisks replacing what I can only guess are unpleasant words from so called best friend. DS seems to be unable to rejoin the clan so has lost touch with the other boys and his 'best friend' hasn't contacted him in any way. They will be going to different secondary schools from September but will be travelling together on the same bus. I am extremely hurt and upset on my DS's behalf. I know he can be a bit silly at times but I don't think he deserves to be ostracised in this way. At 11 I know he's too big for DH and I to wade in and sort it out but we're just so cross about it all.
