My hunch at this point is the root cause is going to be financial. Financial stress mixed with alcohol. No facts to back that up, just a hunch.
jmopinion at the moment, subject to change
my theory is different and based upon his wife's overt misleading representation of the her 'wholesome relationship' with her husband and how that false facade of domestic blessed bliss started deteriorating soon after mother progressively confiding to her daughter. (For some women strife and resignment promotes confiding in another to recharge the self)
It all came to a hilt Thanksgiving evening
i noted no relationship whatsoever between the daughter and step dad on facebook (no likes/post/ or group photos).
Also her employment as a therapist traveling all over the USA (and even abroad to Croatia) spoke of daughter's financial independence and a lifestyle of wonder lust. her coming home AND STAYING awhile there was very out of the ordinary for this boho nature loving people loving concert loving party loving young lady.......
but the things a loving daughter might do for her mom, especially if mom has a problem, or is unhappy, or isn't sure {what to do}.
So that loving daughter...with boyfriend in tow.....makes a right turn, into a wrong situation.
I believe in those weeks in that house Gattis' narcissistic psychopathy changed the course for Mrs. Gattis, who he has manipulated and controlled for years without candy's prying eyes.
That fateful night pschyopathy was the 5th dinner quest, and it helped itself thanksgiving day .
That evening to Christ Gattis there was no Jeanette, Candy and Bob.
And there was no real such thing as right or wrong...there was only what he would or wouldn't do.
