OK, I think a lot of your wife's problem is that she is a spoiled brat. And therefore expects that she can just ask people and they will do it for her. Especially guys. You've said before that she is gorgeous. Well, gorgeous girls sometimes get an air of superiority and entitlement.
I am not disputing your claims of her having a personality disorder because you know her better than I do. But she strikes me as someone that has had everything handed to her on a silver platter and expects that others will pick up for her. Like the tuition payments thing. I think she fully expected you to jump in and rescue her because, well, she's her.
This plays into the manipulation as well. She thinks she can be nice, bat her eyes, flirt her way through life. I told you the other day that I think she can just lead you around by the nose and you will dutifully follow.
I will be interested in seeing how she reacts as you continue to detach. As you are not longer just jumping at her texts and requests. Again, that doesn't mean you are mean or angry. But as you firmly, and nicely, stand your ground she won't know how to act.
