I would like to believe he had a reason for making her kill him.

I don't mind what the author does as long as the characters are happy and well, that the characters actually deserve it(referring to the abandoned empress here).
Moving on will be impossible for our protagonist as long as she stays with her husband, maybe. He and her past love look too alike for it to be a coincidence. Also, she doesn't even know why the emperor staged(I believe it was a farce to get her the throne or something else, still a farce that he knew would get him killed) that betrayal.
