I think that Maggie and Matt share a discomfort with fuzzy boundaries and a tendency to catastrophize along with their canonical tendency toward depression, and they very likely would have been a mutual disaster if they'd tried to live together as mother and son when Matt was young. (Comics canon is somewhat different, in that Jack tends to live long enough to at least see Matt start college -- I guess in that version, Maggie figures he's an adult and okay on his own, which is why she doesn't make contact until much later.)
