Ok. How do you need the help do you think? It's a shame you live so far away. we can't exactly keep a close eye on you! We can't suggest you pop here for a weekend and me flying over is not on the cards at the moment either!
To start, you could email him and tell him you have a couple of upcoming dates and you'll need to be away. tell him you would prefer him to look after the babies on these occasions but if it's not suitable you'll pay to have them cared for. At least this way he knows you have a life and you haven't stopped living cos he's gone.
I'm super busy these days and H is certainly aware of it.
