If your SO dies do you call them your ex?

Technically your relationship didn't really end. It just stopped without any of you expecting it. Do you consider that person an ex, since you aren't with them anymore?

This was inspired by a story I read when a guy married his stepmother after his father died.

P. S. It isn't that weird since he was closer in age to his stepmother than his father was, she was a trophy wife. He also really only met her at her wedding to his father before his father's funeral.
