This is a VERY common scenario in ITALY - where single men can remain living at tehir parents' homes thru even their late 30's. They're called "mamones" (mah-MOH-nays) or "mama's boys" and there is absolutely zero stigma attached to it. See BS's "60 Minutes" did a feature segment on them back a year or two. The typical
mamone is well-employed, has lots of friends, has a girlfriend, and many even have places of their own that they don't live in - until they get married. Their homes are often condos in the same building as their parents' or are within a couple of minutes walk from the parentals'. One guy they showed as 38, had a nice small villa that he owned and it was where he and his girlfriend hung out. But he lived at home, and the girlfriend often visited there, too.
The upshot is that by the time they get married, they've saved up enough to either pay off or buy in cash their own residences.

Yeah, basically the only two upsides I can think of to marrying an Italian man are: dark hair and skin and big italian family with lots of good food at celebratory type get togethers.
