Let's have some female advice, Miss Lynn. Assume the OP is a good guy, what do you think is going on?
IF she married young, and never spent any real time being single, she may be wanting to go back now, and do ALL the things she wanted to do back then, but knew being a wife and being a mother prohibited it. It happens to men and women.
She was home for 14 years, she probably would have been better off being out working, getting away from the walls that housed her day after day.
