M, Your h is far too comfortable in his life, i.e., coming to your home, sitting around, watching tv, sitting outside and just thinking. He could be in this position for quite some time and there is no harm in doing some 180s now.
Go on w/your normal routine, just as if he weren't visiting. Do what you need to do to get your house cleaned, laundry done and if you fix something to eat, do the norm....nothing special for him. He really does need to see that life does go on and no one is going to stop and hold his hand forever.
BTW, not surprised to hear that he's watching tv. I don't think he's watching it all of the time. I think he's napping. Also, running errands and shopping, I don't believe that one. He's just telling you that. He doesn't have the "strength" to do those things on his own. He does them w/the girls or you, but not alone.
M, be kind to yourself...do what you need to do to get to the next level of patience. Step back a good distance and allow God to assist you in those 180s.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
