Bea, He's still in the rabbit hole and still isn't making much sense at all. If you don't want him to contact you w/this kind of crazy making stuff, then I would not respond back to him. He craves your attention and by responding, you are feeding that craving. He will never find his way out of the rabbit hole if you continue to respond to him and feed him the kibbles he craves. The only way that I see him ever getting himself together is when he finally realizes that you are gone, no longer reacting to his behavior, comments, etc. That's why he just may come out of the hole and see the light of day for what it is.
I think I understand why you responded back, but he's not of his right mind and he's not going to "get it" as to what you were trying to tell him. Until he actually is rationale, I wouldn't respond to any texts, emails or phone calls unless they are emergencies. Besides, the man has a wife now who can take care of him, his rabbit hole and yes his emergencies. Time to cut him loose!
