I'll take a stab at this one. CA grew up with three brothers. As the only girl, she probably was considered 'special' by her mom and dad. That in itself is not a bad thing and maybe she was even somewhat of a good girl (good grades, wanted to go to college to become a nurse, etc.) but she was allowed to rule a little too much and her princess needs were catered too. Her brother Rick alluded to the fact that Cindy had always been like that ie, 'bossy'. But LE could not lead him to say she was a liar. We witness CA lying now but in her mind she's protecting her turf. She is overly proud and to put it crudely she has the false sense that her doesn't stink.
Enter George, Mr. Passive/Aggressive. CA probably picked him because he enjoyed her bossiness at first (heck, he didn't want to make decisions) but, after a while, he resented her and all of the decisions she made. Now Cindy is no longer being worshipped and adored by anyone - enter real life. Because she had completed her goal of earning her nursing degree, she had more power than GA in that she held the purse strings. This is not a bad thing in itself except for when GA wouldn't/didn't do his share, which emasculated him further, and then he began doing underhanded stuff, Cindy became overly concerned about being in control. This time CA was chasing the idea of having ANY control because she realized her once adoring husband was crapping all over her and later her daughter followed in his footsteps and, it seems, she tried to fight back by being more controlling. Cindy couldn't/can't let go of her dreams and the idea she has of how her family should be and she cannot accept that her family didn't turn out the way it should have imo. Therefore she looks to be, as she is, delusional.
How does that sound?
