Oh, he definitely loves her. If this were my story, they'd get married even though she knew he was gay, because she does love him, if maybe not in the way most wives love their husbands, and this would be a way for him to live the life he wants to live without having to sacrifice his family to get it.

IDK, at any rate, I have a thing for people of incompatible sexual orientations living together in happy sham marriages so I expect that this fic will make me :DDDDD when you get around to it.
