it would seem to be this is less about splitting, and more about trying to be a constructive co-parent and have a friendly relationship, in spite of her resentments. while it can be difficult, many exes that share children get there.
Thanks that makes me feel better. I always worry about the dreaded split. I can live with resentment. Thankfully she is a very responsible mom, something she's always taken very seriously. She has always been a good co-parent to her ex husband even though he cares little for his own kids.
I'll take constructive co-parent and run with that
