By the way, please could you tell me what it does indicate exactly - I'd like to see it put into words. He wanted me to come and live with him, but he warned me that he is difficult to live with - he DID warn me beforehand and I said I could deal with it. He said he needed me ... and all that.

He is very affectionate when he can be, when he's not tired and stressed.

MIXED MESSAGES !

And he's not taking any meds for it.
He's agreed to get some treatment and has already made a start, thanks to my perseverance. that's why I don't really want to give up on him.
