He Did NOT Dump Her

In fact, we don't know anything about his intentions or what state he was left in.
So, he could have dumped her...

A century in torture pit... meh, i've had worse.
Spectre saying "I don't want to see you again"... pain straight to the heart. (even if he said it to keep her safe)

But i am sure he is really confused and not wanting to trust any woman right now.
Or maybe he's a giga-chad, and is now getting with some goddess on the angelic plane.
