In general, no I would not. I'm in my mid-thirties. If I was 22, yeah it's fine....totally a different thing. In general if someone is living at home by now (well into thirties), it is a result of making very poor choices, getting in debt frivolously, and/or lacking ambition. That is not someone I want to be in a relationship with, especially a long-term one; I could not trust such a person to pick himself up by his bootstraps in the event that life handed us lemons.
