Hiya Plucky:
I can be a real pain in the butt sometimes so no need to answer anything or comment, if you don't feel like it.
Just for you to consider.
I'm still reading way back here:
1. To stay and continue creating the childhood for your children that you wish you had had, minus witnessing a good marital relationship.
"minus witnessing a good marital relationship"
What are they witnessing then, if it's not a good marital relationship?
What are they learning? This is important.
VS
2. To leave and create a childhood for them that may, at least initially, be far from what you wish you had had because you could end up being a strained, tired, financially stressed, emotionally drained, depressed, depleted mother who hasn't done the work to tell what was her fault in the marriage and what was not.
Are you saying you're not strained at all now? Not tired? Financially ok? (probably you're better off??). Are you then emotionally topped up and happy? Are your resources all available, you feel strong, full of energy? (trying to hit the opposite of depleted here....hahaha. Am I anywhere near??

).
I'm going to be blunt and hope that you will believe I'm doing so to help, not to hurt you in any way.
Aren't you just co-existing ? ...... burying some of what you'd really like to say to your husband (repressing some big feelings)? ............... using a good deal of your energy/strength trying to co-exist and maintain control over some of your feelings? Maybe this is why you are struggling with this decision? Maybe your body, your emotions, your gut, your brain.......don't like all that?
How can you possibly be the best mother/provide the kind of childhood you are truly capable of providing under those conditions?
I'm really being brave here pressing "post" Plucky. But not half as brave as you. It takes courage to do either thing....stay or go.
I think you mentioned schedulling an hour for excercise for yourself?? Great idea? How about.....30 min for excercise and 30 min for number 3, way back? (finding someone objective to talk with and support you, so you don't feel so alone, no matter what you decide).
The more you do to help yourself get and feel stronger and happier......the better. No need to hurry up and decide. Either way, it makes sense to get to a point where you are the strongest, well supported, happiest mum you can be? What do you think?
Wishing you peace and strength and happiness ((((((((PLucky)))))))).
OOOOOoooooooooooooooooo (eyes squished shut icon please):
Hit "Post"! Hit "Post"!!!
