This does not require an immediate answer, Claire. Why don't you sleep on this tonight and see how you feel tomorrow. Sometimes it is okay not to respond to everything right now. H's text does not constitute an emergency. Do you know where your children are tonight? Then you can sleep fitfully without any worries.
If possible, why not arrange a quick lunch or dinner with a GF tomorrow. There's nothing like a great pick me up as a good friend.
