Don't be sorry for apologizing, and don't retract your apology when talking to him. You will come out as the bigger person.
I'll admit that "eat s h i t and die" is pretty harsh after 12 years of marriage, but I also understand that there comes a point when BOTH parties need to own up to their contributions to the demise of the relationship. And, it's frustrating when that doesn't happen.
Best of luck to you.
