I believe I can shed some light on his psyche, since I have a *cough* friend *cough* sharing a very similar psychological profile.

Above all, he is a narcissist and a pragmatist. His ultimate and one true goal is to rise, to obtain ever greater influence and achieve unfaltering respect from his peers for his achievements.

Men like these don't survive naked in the cold. Men like these wear skins, fashioned in detail to match the expected social behavior of the environment they're in, serving as psychological and social armor for their innermost, purely analytic self. A man knows a skin as these must always be worn, lest the shame in being seen in true nakedness would lead to the collapse of all one's achieved so far.

It is through the wearing of these skins that one "fools others", and, in parallel to Bloodraven's warnings to Bran on staying in the past for too long, wearing them for too long makes one fool oneself, to the point where one may no longer be able to discern them for what they are, being lead to believe they have become a true part of their inner self.

Emotion, love, is always the innermost skin, but a skin nonetheless. Being beneath thicker layers of skin, this one is rarely exposed. Similarly, something affecting this innermost skin has longlasting effects, echoed through one's motivations in a very real sense.

However, much like snakes do, skins can be shed and replaced.

He did love Cat, and he does love Sansa. And that is very real to him, due to the quasi-assimilation of this innermost skin. But that too can be shed, not without great psychological pain, but it can, if it enters in conflict with his inner core.

I'd still call that true love. Just not a form of true love which surpasses pragmatism.
