Rottman,
I can relate to what you are saying. Though my H doesn't monopolize my time, there is definitely some allure to having no one to answer to.
I read a great quote about that very thing on this website a couple of weeks ago, but can't remember where. Something like, There is a certain amount of loss of independence that is built into marriage. It's not necessarily anything that the other person is doing or not doing, it's just part of being married.

This helped me because I at times feel a feeling of being trapped.

Let me ask you this:
Do you feel that you need novelty in your life? Was part of the allure of the EA that it was new...and that added to the escape sensation?
