Well, I can certainly agree that they can only truly start to reconcile AFTER the A is over.
But the root of the problems can begin to be addressed long before that, and really should be, regardless of what happens with the A and the M.
I can agree with that too, so long as he's not looking for much in the way of
a) response from her to his addressing his flaws; and
b) having his emotional needs met.
Because neither of those are going to happen so long as she's still a-gaga over OM. But yeah, he can -- and should -- immediately start to work on his own issues, as he perceives them to legitimately be.
