Because with the kid's in school I had way to mch time on my hands. But also this gave us extra money that was much needed. My husband wanted me to work more then I did. I think he was very resentful he was the sole bread winner.
I can understand why it would threaten you if you have been in an unhappy marriage. After you have been A SAHM for years in an unhappy marriage going out into the work force changes you. Because you start to realize you are a lot stronger then you think. You no longer rely on your husband to provide for you. But most of all you start realizing more that you have a lot more power to make changes to make yourself happier.
