Thank you all. You don't need to "protect" me, though. You all helped teach me how to protect myself.
CeMar: No, the "safety" she wants is not solely money-related, yet she points at some of the things I did in the past as adding to her financial insecurity. No, "safety" to her is, uh, let me think, hmmm, oh...whatever vague thing it is that she can point to at the moment that she is feeling. It can be that I told her a white lie. Or that I spent $5 on a car wash. Or that I missed a spot on the window. Or that I didn't tell her about something my ex did. Or that she's bothered about something my ex did, and why did I have to tell her about it? etc.
