Ex husband and his crazy family

I have nowhere else to vent. Can’t vent to Facebook. So I’m coming here. I have a daughter who’s 14. Her father hasn’t been in the pic for 5.5 years. We have a court order from Feb 2020 stating he was to pay for therapeutic visitation for 8 weeks to “connect” with our daughter. He never did a single thing with. Fast forward a couple years. He remarried to his third wife. That lasted a year. They divorced and now he’s with someone else and they just had a baby. His 5th child with his third baby mama. I’ve been harassed by his family and their friends to the point I had to file a police report against them. My daughter graduates 8th grade next month and my biggest fear was him and his family showing up. Last week he apparently called the school asking about graduation but I had the school take him off EVERYTHING that regarded my daughter. Now I’m in fear of him and his family showing up next month ruining her special day. She is absolutely terrified of them. And I’m just mad. Anxious and irritated. I’m at a loss at what I can/should do. My husband who has been her father figure since 2015 spoke with our lawyer and the lawyer said her father can be there in the back row but if he were to come up to her. Then it all changes because he’s not allowed around her. I’m in full blown mama bear mode.

Edit to add: my husband now was married to my ex husband’s half aunt. This woman is the one who harasses us any chance she gets. I’ve already filed one police report on her. I even have a Zip drive of her harassing me 3.5 years ago at one of my daughter’s concerts. I honestly don’t think it was my ex calling the school. But this woman’s husband (he used to work for my husband) just pretending to be my ex. My daughter doesn’t even want to do her 8th grade walk next month because it goes past their house and she fears they will be outside. She has ADHD/ODD. So in her mind she thinks this woman will take her
