Answers: NEVER did they show the girlfriends of those two. Also, never did those two ever talk about women in the show. They also never mention that they have girlfriends. I'm thinking those two are gay and they love each other.

Not that it makes any difference though. If they have families it' because they adopted or they haven't come out of the closet yet. I totally think they are (not that there's anything wrong with that) gay. But that's only my opinion. As far as I know they are married with children.
