I am not surprised that Shep is single, he really is not a nice person, friends are only friends when they fall in line with him. He has called Kathryn and Madison "White trash", of course he wasn't thinking that when he tried to hook up with Madison, who rejected him and during the multiple hook ups with Kathryn. Why is it they are only "White Trash" after the fact? He claims their "upbringing" was poor and they have no manners, well surprise! A man who acts and speaks the way he does, is Elitist trash, who has forgotten basic manners. Maybe he should quit drinking to excess and do some personal introspection to figure out why he can't keep a relationship.
