Welcome to the best worst place to be during this.
I have read your thread and I can see how you fit the model of many women once we start raising kids.
I can tell you that finding yourself again will make you much happier in the long run. And it will ease the empty nest thing once it happens.
Perimenopause is no joking matter, I have been going through it for a while now. Be good to yourself.
As far as your H, as you know, MLC lasts a long time and it doesn't always work out the way that we want it to. Only you can decide what is best for you in this situation. If you think you can live close to your H and still have your own life then go for it.
I like your list but you are right, it's daunting.
What on that list do you consider fun? Maybe instead of a non fiction book, read fiction. Something you can lose yourself in. Personally, I find that books like Harry Potter, while written for young adult, allow me to just relax and enjoy the book for what it is.
Anyway, keep posting, people will be around.
