My SD and DH had a falling out 7 months ago and SD moved out. On her way out she said some really nasty things about her dad, threatened to call the police (for items she left behind and wanted) and stuck us with a car payment once she procured a new vehicle. She refused to speak to DH for 6 months. During that time her and her BM posted disparaging memes on FB about DH and she posted pictures with DH 2nd wife's kids (who she supposedly hated and had bragged she broke DH and wife #2 up). On her 21st bday I encourged DH to post a "happy birthday" message to her.
