In many cases it has taken time for the the spouse to build up the emotional dettachment. The ability to move on to not care anymore. Whatever you want to call it.
Telling the spouse about "Divorce Remedy" or your plans to change, or how you want to try, and this time you really mean it, tend to fall into the initial reaction of: "Too little, too late."
You're basically screwing with a long term plan of theirs. A decision they had finally come to because nothing else worked, and really? Why is it going to be any different this time?
Ignore the flat attitude you got, and just prove her wrong. Not by telling her she is wrong, but by showing her that she is wrong, consistently and over a period of time.
And for the love of God and all that is good, do not tell her about this place. This is your safe place; and ours.
