Wen, I am just imagining your ex being pissy with OW, since she is the cause of him having to finally move out of his comfy home. And she is the cause of him having to buy new food for his new kitchen. And she is probably going to be pushing to come out and live with him now that he is FINALLY free (which, obviously, has not been a priority for him or he would have finished living with you a LONG time ago).

Just can't help but think that with all obstacles to being with OW now removed, and you with a nice younger man contractor renting the guest house.......well, let's just say I'm picturing a decidedly uncomfortable week for your ex.
