My fiance and I had an accident
the other day - I dropped a bottle of wine due to a sudden burst of pain (I have chronic migraine). Part of the bottle hit my fiance on the head, and a shard made an approximately 3 centimeter incision on the side of one of her nostrils - I have no idea why. We immediately went to the ER and they glued the back together, and gave her a CT scan just to confirm there was no concussion from the bulk of the bottle that hit her head (there wasn't). The hospital staff agreed that it was an accident, and found absolutely no signs of abuse.
However, my fiance's mother, upon hearing she had been in the ER and sliced her nose, assumed the worst, which she communicated to the divorced father and several other people. The father has proceeded to treat it as though I swung a heavy wine bottle at my fiance's face with a clear intent to harm (and somehow, only caused something that now looks an awful lot like a papercut on her nose). After my fiance explained and we emailed a picture of the injury to the mother, she calmed down, but after the same explanation of the incident and sent picture to the father, he escalated, continuing to insist I had hit her, spreading the word to various family members and causing significant issues for us (my fiance and I), along with emotionally traumatizing her.
He's gone further, making veiled threats aimed at me, as well as claiming I'm a "no good unemployed druggie" because I'm self-employed (due to my pain condition, which he is aware of, making my work schedule unpredictable, so I formed my own Limited Liability Company) and take pain medication, which is 100% legally prescribed for a pain condition that's been diagnosed by multiple doctors.
His claims range from extreme exaggeration (I do take pain meds; I am NOT a druggie) to flat out lies (I am not abusive.), and he's harming both my reputation and the emotional stability of my fiance. He has absolutely no proof, only his daughter saying she's never been abused by me and a hospital that found no signs of abuse.
Is it actually legal for him to do this?
