See, I feel that she really DIDN'T want to go on that trip, but she really wanted all of THEM to go on that trip. I think the whole PR trip was her idea. She knew damn well she didn't have the money to go on any such trip, but she did have a facade she needed to maintain. "Let's all go to PR!!!!" Plans everything out, including flights, possible activities, texts about what she's gonna buy for the trip and take with her. Should she shave/wax, blah, blah, blah. She's a thief. What better opportunity to steal from her nearest and dearest, than while they're all out of the states, in Puerto Rico?
She didn't want to move into any house/apt. with Amy (many stories made up as to why the house/apts. couldn't be viewed.) She didn't want to go with Amy to Jacksonville to buy a new car (dad had mini-stroke, on the way to the hospital, he gave us all a big scare, but now all is well.) She didn't want to go over to T.Rusciano's house for sex/hanging out (the nanny is delayed, driving back, had to stop at her sister's, had to stop to pick up her dog, traffic is a log-jam, waiting on Mom 'cause she owes me, Mom now can't move her neck, etc. bull**** stories.) She didn't want to really meet up with WW after he kept asking when they could get together, etc. (text, text, text, to keep him at arm's length.)
She was all about Casey, and Casey alone. If you didn't further her cause, you were "a Waste, a HUGE WASTE!"
