I'm so sorry for all you are going through and have gone through.
As you can tell by your experience and your information on this site and Divorce Remedy, you have found some things most often don't work, and even make the situation worse (like begging and pleading).
You have also seen that it isn't hopeless. These situations can and do turn around and marriages like yours can become more loving than ever. You can also tell, that going to counseling doesn't solve the problem
You also do not -- for awhile -- need your wife's 'cooperation' to turn your situation around.
So, begin afresh with a new mindset. I welcome you here where you will find folks that can help you brainstorm new approaches for changing your situation. Focus on positives and folks with positive solutions to offer.
So, on that note, what is going well between you and your wife, and what is going well in your life?
What were the things that initially attracted you and your wife to each other?
What are the positives that have gotten away from you -- things you used to do back when you both were happy?
Wishing you every good thing and every blessing
