Basically, he will either run away from the problem (classic avoiding responsibility again) or act like a small child throwing a temper tantrum and suddenly it's clear where the name came from.
If the guy you're seeing is only well-versed in toilet humor, and makes the type of jokes that are actually offensive to women, then he has a lot of growing up to do.
This sense of humor could come from a place of insecurity, or this guy could legitimately think these are the only things on the planet that are truly funny. The man-child seems to be popping up everywhere nowadays; the more difficult it is to get a job, and the deeper in debt we crawl after college, the more men are choosing to revert back to their pre-pubescent ways and avoid all of the scary things the adult world has to offer.
If he's between jobs, and actively on the hunt for something suitable, that's one thing.
But if he's too busy with beating the latest version of Grand Theft Auto, that's another story entirely.
If he even cleans his plastic spork, and Styrofoam bowls is another question entirely. Man-children do not have the word responsibility in their vocabulary, so chances are when they are met with the foreign term, they deny its existence entirely.
Whether you are asking them to rightfully take the blame for something they have done wrong, or telling them that, yes, their landlord will notice if they decide not to pay rent this month, this guy just isn't willing in any capacity to confront all the things that come with getting older.
Man-children often do not know what makes for a healthy, balanced meal.
Often, they are found to be eating food teetering on expiration, or things that have colors you cannot find in nature.
Being the breadwinner in your relationship is awesome (you go girl!
), but having to cater to a man who doesn't want to get off of the couch is not OK. The man-child is aware that his space is filthy but, he doesn't really care to change it.
Not to make generalizations, but the men out there I've experienced are pretty crappy when it comes down to conflict within relationships. Unlikely to want to confront his emotions because he has not come to terms with them in a grown-up, healthy way, he'll avoid the problem entirely.
