I am confused

One of these people used to be a man but now is a woman, the other used to be a woman but now is a man.

They got married.

A subhead at Never Yet Melted:

‘Britain Sinking Into The Sea’

"Transgender Army officer Hannah Winterbourne has married actor Jake Graf — who used to be a woman.

"Captain Hannah, 31, who spent her first few years in the Army as a man, wed Jake, 40, in London.

"The delighted bride said on Monday night: 'I never thought when I was younger this could happen to me. It was always a pipe dream.'

The wedding, he/she or she/he said, was “like a Disney movie.”
