Thanks for coming back to share your insight. It's always good to see things from a different perspective.
I think there's always a difference between the dumper and the dumpee whether it's in marriage, a relationship, friendship, employer/employee. Maybe initiator and recipient are better terms.
The initiator's decision is never easy to make. It's never made lightly either. And it's usually a long time coming. But once it's made there's a new mindset and direction. Of course, the recipient is confused, surprised, shocked.
The initiator (who could be either spouse) makes a choice, a decision.. and the recipient has no choice but to catch up. The recipient is caught half dressed and shoelaces untied when the fire alarm goes off. Like you said.. someone might ask you what car you're buying and the answer is 3:30.
Two completely different perspectives.
In the end it comes down to acceptance.
Getting married is a mutual decision. I think a divorce should be too.
