Ok, think of MB as a structural surveyor. If it can underpin the foundations of your house and help to correct the structure of your marriage, then papering over the cracks and redecorating will not only be satisfying, but your house willnever look better.
If, however the structure is so bad that a total rebuild has to take place, then , if you don't involve anyone else in your life at this stage, the decision has to be whether to move or start over.
Difficult decision, but I would explore every option before making that decision.
