I do a lot of comedy on the subject(why do divorces cost so much? THE'RE WORTH IT) But in reality a divorce is a good thing if you need one. Please, please, please do not stay together for the sake of the kids. It's not their problem unless you make it that way. They NEED for you to be the best, happiest, most content productive human you can be. Continuous confrontation between their biggest role-models is just not good. I was married for 25 years while being a full time musician and did not know how easy a relationship could be until I met Chris 12 years ago. A mediocre marriage is a lot worse than a mediocre band on EVERYBODY.
