CTH, its still new. give yourself some time. you're doing fine.
the more you think about it, the more you'll thing about it.
a couple pages ago you mentioned how xw was somewhat pushing herself into your schedule.
years ago i read a book by M. Scott Peck called People of the Lie. in it he discussed "The Narcissist: Coercion and control of others". one of the case studies was of a women who would run out of gas frequently and call others in the middle of the night to come get her.
she acted as if it were nothing, just a funny little adventure they shared saving poor ol' forgetful girl. but it was really about control and manipulation.
what you wrote reminded me of that book. whether or not your xw is doing this is not for me to say, and i dont mean to imply it, it just triggered a memory.
