If you ever listened to the podcast she had him totally brainwashed exactly where she wanted him. He was like a puppy dog and couldn’t believe she was interested in him. She is a narc and he was good for her for awhile because she needed to get back at Matt and posture her new relationship as better and Brendon as the best step dad ever. After a few years she realised Brendon was a bit of a dud and after working with a different more successful type of man at the new role she realised she was a social climber and could do better than Brendon in terms of money, looks, influence, arrogance etc.Interesting theory - why do you think that? Definitely possible.
just my theory could be very wrong!
