51, right? Congrats! Boy, what a CONFUSING relationship you have, and how difficult it is to get any "detachment" space. It seems like you spend a LOT of time with a woman you will eventually divorce. At least my STBX hates me ALL of the the time, and that has made it much easier to detach. Is she "borderline" or what?
Good thing she bitc6 slapped you for letting your daughter watch TV while doing homework. (I hope you let her eat a can of frosting and Oreos for dinner too. Make it worthwhile to get your as& handed to you!)
