Wow that sounds rough... my W has stepped up and is still honoring her responsibility as a M, more so now actually then before when we were together.
I don't agree that Kids are resilient - they will get through this but no doubt will suffer some damage, however I've learned that they can also be a great source of strength for us through this. My D last night was reading her kids bible (on her own, and on a night when W was looking after her) and this morning was citing the 10 commandments to me...
During Easter she asked to pray the ways of the cross with me. God works through them in amazing ways!
Even if you'r not religious - your D7 can be a great strength for you and a source of companionship while your W figures her $#!7 out.
