My train wreck

So long story short my family member who I will refer to as B stole a little over $50k from me. Anyways after stealing the money she picked a fight with another family member C and used the situation to make herself look like a victim to her fiancé. C and I both quit talking to B and B fled the state. B is an alcoholic and recreational drug user and also an RN. B gets really violent when she’s drunk and is known to drive drunk and physically attack people. So B’s decided even after seeing what she is like still thought buying her a very very expensive engagement ring (she told him she wouldn’t marry him unless he bought her a ring worth at least 15k because she deserved nothing less) and went ahead with the nuptials. It’s been a year and they’re now getting a divorce. She hadn’t talked any of our family stating that her husband had forbid her from contacting us. Under the context that he thought we were bad people. Anyways a couple months ago B got really drunk and popped a bunch of downers after her husband filed for divorce. Another long story short her husband and best friend had her committed for threatening to commit suicide. While committed her best friend and her husband reached out to her father who I’ll call D. The husband told D a really interesting tale that was like wow. First off the she tried to take off in a drunken rage in her car and crashed. She somehow managed to get home before the cops arrived and told them her husband wrecked the car. Of course she had bruises and burns on her face from the airbags. I guess B also told her husband horrible things about D, myself and the rest of our family and he said that he had never forbid her from speaking to us it was just her not wanting him to speak to us and finding out the truth. I also guess she was had lied to her husbands parents about their financial situation and was receiving $1k a month from them. Which her husband had no idea was happening until his mom started to doubt the story and caught B in a lie. Come to find out B hadn’t been paying any of the bills and had just been pocketing the money. Now B is having to move to get away from the people there she screwed. I’m afraid of her moving back to my area and starting trouble here. I already told D I’ll have her trespassed if she comes to my property and do what I can to file a protection order. It’s frustrating that the nightmare B can’t just stay away.
