I don't gain anything from talking to a cuck or a post wall roastie, so I'd just declare the post wall roastie as my "wife" and let the cuck be our servant. He is allowed to watch if he wants. If he disagrees, we would settle it with a fight.
I know this is the typical way men fight each other for women which isn't very based at all, but there is no way around it if he doesn't assume his position.
