My XAH was also a functioning one but only as far as the job goes...and I don't really think that was going well either because he was driving and drinking staying out late in the company truck. He also walked away from us (2 kids and myself) to party with a party girl and all I have been hearing is that she may be done with him...go figure that....she's done with him?? Well.....she grew it she can chew it. But anyway...he wasn't as functional as what alot of other people thought he was it was an illusion he created to the outside world. The kids and I knew better though. We could see that something big was about to happen and that was when he left the family high and dry.
