Coffeelover...I'm sorry this realization has been so painful for you, but it *is* a good thing. Have you told your AH that he's not to overstay his welcome? I'm just concerned that he might decide to hole himself up in your home and not leave. The logistics of getting him to leave then are more...complex.
Perhaps it's time to take legal steps to prevent him from coming back at a later time. Talk to a lawyer and see about filing for temporary exclusive use of the family home.
