He can be a jerk!snob sometimes and overly blunt, but Ellie is like family to him - so he'd treat any relation to her with respect (though he might jokingly give him hell because it's just who he is.) He's the chief branding officer at Tiffany's, married to former republican politician, and raises two kids (13 and 11) with his lesbian best friend. Matt was someone Ellie confided in about everything, so I can see him feeling awkward around him back then.
