Maya/Adolin are catching some serious splash damage with this one. They have one of my favorite relationships in the Cosmere and it's not at all cheapened by Adolin having an entire wife.
Re:male loneliness epidemic stuff, yes, if the only reason guys can think of to talk to women is that they might get a girlfriend, and platonic relationships don't make them less lonely because they can only be emotionally vulnerable with someone they're sleeping with, that DOES sound like a recipe for misery! Fortunately, both of those can be solved without having to be in a relationship.
