The advice I was given was to let your W tell the kids that she wants a D...if this is not what you want, it is ok to tell them that YOU do not want a divorce...I can't help you with the wording. If you google "how to tell kida about divorce" you can find a lot of info.
Sorry you are going thru this. I got stuck telling my kids myself...
As far as the concert, all you can do is ask your W to respect you and not do it again. Unfortunately, there is probably not a law against that!
