Ad - Sorry I didn't realize you were asking a rhetorical question... my bad.
I get you wanting to teach your sons something - so take this next comment/question from someone who has no experience raising a child.
But are you just teaching them or do you believe it to be true yourself?
Are you honoring your marriage because of the legal contract part of it or the promise to love for better or worse?
I DO believe the latter to be true for you in both questions ^^^^ but you did mention that signing a document would be "the end" for you.. so I'd thought I'd ask.
FWIW - it doesn't end when the Divorce is final. I don't have any connection, children, friends, or whatever with my exw.....
... and I still uphold my vows.
I uphold them every time someone wants to talk sh!t on her. I uphold them when she did weird stuff. Mostly I uphold them in my heart that when life gets tough and I am looking to blame my sitch..
As they say - it's never really over.
