It takes 2 people to wreck a marriage, but it also takes 2 to put one back together. And if one person chooses to blame the other for all the problems and fails to look at their own contribution, it just won't work.
I asked for several years to go to marriage counseling because I could see that things were going bad, but he always said I needed counseling because it was all my problems, he wouldn't go. Maybe if I had gone to counseling on my own things might have changed, but no use wondering now. And I doubt he will ever recognize his role in the failure. The only "apology" I ever got from him regarding the demise of our marriage was him writing that he was sorry that he wasn't strong enough to carry us through all of my problems. Sad but true, that is the only "fault" he has ever claimed
