Like muppetWrangler I went through a similar thing (also without the children) a good number of years ago. The NHS move impressively quickly when they need to. My husband had brain surgery – I remember I had to keep saying that quietly to myself to try to make it compute. It didn’t seem to make much sense that he could be having brain surgery.
Anyway, I don’t have many words of wisdom but a couple of things which may help. When he was coming round from surgery I was understandably anxious about what was going to happen, whether he’d be the same person whether anything would be changed, personality wise. He was the same guy, same quirky sense of humour (I don’t believe it’s recommended when the Docs give you the test questions such as What year is it, What is your wife’s name etc. to answer the Who is the Prime Minister question with an idiot). The thing which startled me was that Dave was also worried about whether he’d be the same person, and was reliant on me to tell him that he was. Bear in mind it may be a fear of your wife’s as well. May not be, we’re all different.
The second thing is to remember to laugh. Like a steam valve, but laugh together, because sometimes the entire thing is too bizarre not to.
They let him out quite soon after surgery, less than a week later, and still with the staples in his head. That was pretty cool. They left us with multiple warnings about epilepsy which, for quite some time, made me worry about leaving him alone but needlessly as it turned out.
You’ll be in my thoughts. Don’t forget to laugh.
