Per your linked suggestion, I read.
You fathered a child at 61, and your piece criticizes nearly every step your wife chose, and then takes a minor stutter back to say "I don't blame S..." but you do.
For cosleeping, for overspending, for lack of intimacy, for breastfeeding too long. And you laud yourself for being emotionally available, for "having resources," for offering up your best self at every turn.
And much of what we see is that not only she, but all women, are just not up to the task.
Perhaps if everyone in your orbit, including your own family, is suggesting you stop blaming her - well...then maybe stop blaming her.
