Nell, you won't get any kind words from him in emails, texts or otherwise, my H has gone back to the matter of fact emails with no emotion whatsoever. It is what they do regardless of the length of time in between seeing you or talking to you, they have checked out so to speak.
I have read on a few posts but I can't remember which ones, that reiterate that they still do love us but it is buried deep under all the other crap going on in their heads, they have to find their way out of all that to find that love that was and is always there.
I am sorry about your headache, take the panadol and perhaps try and have a lie down and slowly try to relax your body and let your mind wander to something pleasant, I sometimes find that helps to relieve the tension which will be behind your headache.
I wish I could give you a real hug Nell, there is nothing better than human touch when we are down.
