I had d8 Thanksgiving day until around 3 when I dropped her off with uBPDex's parents so I could go shopping that night. I've been dating a wonderful man for several months now and had spent the day with new guy and his family...ex knows this. I had just pulled out of my drive to head out to the stores when ex called and accused me of telling d8 that new guy is going to be her new daddy. I told him I didn't have time for this nonsense and he put d8 on the phone and she said his mother told her that. I explained to her that she has only one mommy and daddy and she said she knew that already.

(Come to find out, his mother did say that and said she was only joking)
So he left me alone the rest of that night. Last night, after picking d8, he calls again and I let it go to VM. Once again, he's spewing his nonsense...accusing my s16 of telling d8 that her mommy and daddy won't get back together. He goes on to say that he's been nothing but good to my s16 (excuse me?) and he's allowed s16 to volunteer at a local haunted house event that ex has been volunteering at for many years, and when s16 was volunteering at a local fish fry and ex, his family, and d8 were there - they invited s16 to come eat with them on his break. He also said that he can't help it if s16's dad doesn't love him, but he won't let anyone ruin his r/s with d8.
I texted him and told him he needs to worry more about his own family trying to ruin his r/s and leave my children alone. He didn't say anything else after that...but I expect to hear more today eventually.
