BQT - I have no advice as I don't really understand your H at all. I worry that he is using you at the moment as you have a car and he doesn't he has a baby sitter for his S, its all rather perfect as he can come and go when he wants and leave you stranded.
What if Hannah had been really sick and it was the doctor's or hospital you needed to get her to, what would happen then. I think it is wrong you having to bundle up Hannah at night and take her in the cold to the shops on your bike. He could ride the bike to where he is going or catch a lift. It is your car and you should say if it is to be left at home.
Anyway that is just my opinion although I think NYS shows you a good point. You do what you need to do to make yourself happy......KDU
