Everything reported about this man makes me think psychotic personality disorder. Not 'psycho' as in the film with the shower curtain scene -- not psychotic, but psychopathic.
Manipulative, arrogant, shameless, callous, remorseless, self centered to the Nth degree, glib/shallow emotions with the capacity to completely abandon a 'loved' one and hurt her deeply (by telling her the pregnancy is inconvenient, clearing absolutely everything he claims to own out of the house while making a big fuss over missing the cats, trying to get her to feel sympathy for him in earlier texts, etc..).
Grandiose -- pushing his options onto her, like the counselling (see his high handed tone there) and the abortion suggestion to both of the mothers of his children, with (I would bet the farm) no idea that these women would hold a different idea of what should happen. It must have been a shock to him that the OW wouldn't play along.
Need for excitement -- hence the OW. Risk taker, spineless..
He would see himself as perfectly entitled to withhold his address from Lou while also entitled to roam freely through his house that he has left -- yes, I know that he is legally entitled to, but there is a difference between legally entitled to and taking account of the other aspects of the situation and decently asking Lou beforehand. He will rationalise what he did on the grounds that he is legally entitled to.
