I'm sorry to read he's taking the MLC route, but they all try to make themselves feel better w/bright and shiny new toys. Once the shine has tarnished, they move on to the next toy. Hopefully, in time, he'll come to realize that all of those toys will not help him find that illusive happiness that he's seeking. I do hope that one day he'll realize that he had a good marriage and family. It's so unfortunate that they have to be destructive in getting to the other side.

Please take care of yourself. Do what you think is best for you and the children.

Sit quietly, the answers will reveal themselves when you least expect them to.
The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
