I agree with MNG, be prepared, and keep your cool.

Or GET a cool to keep, lol. Borrow one if you have to.

Have you read any of the stuff about push-back, change-back behavior? With a reluctant spouse, they are often reluctant because the way things are WORK for them. They shouldn't have to do anything different, and sure don't appreciate you doing anything different (like expecting care from them). So, during the change-over to a mutually satisfying and beneficial marriage, they will scream (you can safely ignore this). Eventually, with *consistent application* of MB concepts, they will see how it creates something better than what they had and thought they wanted.

However, going from A to B is not a short trip through candyland. There's no puppies or rainbows. It's more like hellfire and dragons. BE PREPARED, and be cool, calm, and collected. Eye on the prize and all that.
