There is no way of knowing if the two of you have achieved permanent change. Actually, the second I typed the phrase "permanent change" the oxymoron was self evident. It's really a process. It could actually get better. She could ask to do you on a Tuesday morning or for a double dip on a Saturday night. If that happens, hey, have a good life and come and visit us sometime.
Maybe you should just count your blessings for the positive things that have occurred. And most of all, thank your wife. Buy her a flower. Make her breakfast Saturday morning.
