The only thing you can do anything about is you. Make a conscious decision now to not beg or plead anymore. She already knows how you feel. Start taking better care of yourself right now, eat right, get as much sleep as you can, exercise regularly. Do not try to change her mind. I know it hurts, and I know it's hard. You must do this, no matter what. You gotta do it for things to work out, and you gotta do it if things don't. You have nothing to lose and everything to gain by investing in yourself and your growth and development.
This x1000.
I know you want to save your M, or else you wouldn't be here. None of us would be here if we didn't want the end result to be with our spouses in a much better place.
The truth is, you will never regret taking the time to invest in yourself and become the best person you can be.
Your W is on her own journey right now, and as hard as it is, you have to let her go through it.
