Whitney and her whining about the in-laws taking time to accept her reminds me of a relative in a similar situation. Their son met and dated their former DIL in high school, and married her after they graduated from college. She had been a part of their family for years, and they love her. She is also the mother of 2 of their grandchildren (I assume, as good Mormons, Justin has children with his ex, since that seems to be a marker of being successful in life/faith). My relatives LOVE this woman and made it clear to their son, that she is considered family and would be invited to family gatherings and yearly visits to DisneyWorld (in the Before Times). Like Justin, he married the other woman. I have no idea on mantle picture status though.
She seemed to have no understanding or compassion for what Justin's (that is his name, right?) family went through. Can you imagine being blindsided that you're son, in his 40s, has betrayed the woman you have accepted as your own daughter (and their children, assuming they had some), for a pole dancing, squeaky voiced. bleach blonde that wants to get laid.
