Oh yes, he's very self centred! Part of it is that he can never acknowledge my pain because it is opening himself up to more guilt so I learnt a long time ago not to expect any sympathy from him.
He's usually in a good mood and is fairly even natured. In more recent months he initiates conversation and his sense of humour is apparent. He laughs and goads, but mostly children. Will look at me when kids respond. However, he doesn't usually initiate contact except when it suits him; usually weekends. For example, will take my daughter to a game Sat night and then call in for a chat afterwards.
