Dear MonaD:

If he had a difficult childhood (and so many of us do), and he is now living with his parents or he is in a regular contact with his parents in-person, being physically there,  it may be that since he is living with them his childhood emotional torture has been activated and he regressed from the affectionate, sensible person that he was when living away from them, to the cold, selfish person he’s been with you living with them.

Do you know anything about his childhood/ his past and present relationships with his parents?
