It took me a few years, but I finally put my ex-wife behind me.
No, not just the lawyers and paperwork and financial stuff. Or the emotional stuff.
I literally put her behind me. A microsecond behind me in the space-time continuum. And as long as she is out of phase with the universe, she’s out of my life.
This also solves the joint-custody problem with the kids. She can see them any time she wants, even if they’re just echoes of themselves.
Her lawyers say this is unreasonable. So I sent them back to the age of the dinosaurs.
