Some people are considerate (the ones who are ready to be parents) enough of each other and will not tell the other to "Get over it" or "Snap out of it".
In case you want to know my qualifications for saying that...
I am the product of a dysfunctional family AND the product of divorced parents.
How happy are your kids going to be? Marriage partners are not the only consideration, do you dare forget about the kids? They are your legacy. Because of their love for their parents, they might someday address their suicide note to you like my brother addressed his suicide note to my mother on my father's birthday (because my brother didn't GET OVER IT).
