Another mumsnetter awake here...
I'm so sorry that life as you knew it from now on will be much different to the life you imagined.
The only positive thing I can think of, is at least he's not keeping you hanging on to a dream.
You have the opportunity (in time to come) to put your best foot forward, and show him (but most of all yourself), that you are a level headed strong woman, and you'll use this unexpected turn of events to seek out maybe a new job, or a new qualification.
I of course can't know your circumstances, but for your own prides sake, please don't let him think that what he's decided will break you.
You bloody show what you're made of girl, and then when he wakes up to realise what he's thrown away, it'll be him that has the lifetime of regret.
Me? I had an awful blockage in my digestive system.
I have taken slippery elm in appropriate doses, and tonight I feel so much better.
I'm sleepy, but I've nodded off sporadically throughout the day, so I'm not quite ready for the dream express train.
Do you have dc op?
I do know that makes it harder.
It did for me when my marriage went down the pan a million years ago.
Even tho it was difficult, my dc was happier (actually slept through the nights) with one happy parent, than having two parents that are not.
As much as you think you can hide it from the kids, they kinda "know" something is wrong.
I knew it with my parents, and it's an awful burden for a dc to carry, as from experience, I sensed an awful lot, and tho I was young (pre-teen) I begged my dm to leave.
It probably feels like your whole world has been turned on it's head, and if you're not yet upset, it might be because you're numb with shock and cannot process it all.
I'll bet it's not bothering him, and he's snoring his shitty little head off.
Sending you strength, and positivity.
