As most folks know, in a divorce, especially one that has kids, they suffer when both sides don’t get along.
Betrayal, hurt feelings, and resentment make for a bad time all around.
But as a man, you have to stow your feelings, and move on with the ultimate protection of the kids in mind.
I don’t care what she did. It’s immaterial now as you are getting divorced.
Your love is now dead, now your relationship is a ledger with credits and debits. Your contractual agreement now must be figured out.
And the best way to move forward for both parties, is to act like adults.
