FP, I feel your pain. My dad has also been caught stirring up trouble for me. He recently claimed to be anointed and didn't like something on my Facebook. He spoke to my (former) elders and CO. He banned me from his presence at a family gathering (which was sweet). And he has slandered my name to every JW family member within a thousand-mile radius.
The good news: I recently discovered he went to a strip club a few years back. He doesn't know that I know. I'm just waiting for the perfect moment to bust him on it, probably when plenty of family members are around and he is slamming me for "leaving Jehovah."
Revenge really is a dish best served cold...
