I've (50M) been struggling with a deteriorating marriage for two years. Today was another conversation in which I apologized for things I was responsible for and she did not apologize for things she was responsible for; she just explained to me why I didn't need to be upset.

Part of me wants to ask for a divorce immediately.

My doctor has told me I should at least give couples counseling a try...my wife (49F) has finally agreed after a year of stonewalling; we (err, me) are actively searching for counselors. My former pastor, who is divorced, said I should consider waiting until after the New Year because splitting right before the Thanksgiving and Christmas holidays can make those first two holidays in separation really raw for kids. (we have one, age 15M)

I'd welcome advice on whether I should wait? Go to counseling, even though she seems to have little ability to self-reflect?
