feels like i am on a rollercoaster

I say cancel the vacation as your first step of detachment.
DB is a long endgame. Be aware that there is zero chance of turning this around on a Vacation. Just my humble opinion though.

This is good advice. I should have clarified in my post, cancel it.
You're not going to have fun anyway, last thing you want on a vacation is stressing about your marriage.
