How can I stop my step mom from harassing my family? She has gotten a protective order against her son, when he has not did anything. She tells lies to my friends and step brothers female friends. He has had no contact with her since before she got the protective order.
She was married to my dad for 27 years and has always had mental problems. We have always put up with her talking bad about our dad because he wanted us to just to let it go in one ear and out the other. Our problems didn't start until my dad became very ill and she would not let us stay there and take care of him. She would not care for him. He lost 20lbs in 3 weeks. The only thing that kept me from calling adult protective services was my dad and I begged him to come and stay with me but he was afraid of him. She mentally and emotionally abused him and he was just too sick to do anything about her. He even had me get his gun because he was afraid she would get it or that he may need it for protection.
Now she is telling people that her son and I killed my dad plus a bunch of other lies.
I don't understand why she is doing this when all we want to do is forget she ever existed.
My dad died and I hold her responsible because if he would have been in better shape-nutrition etc; then I believe he would be able to fight the pneumonia that killed him.
He spent 3 months in the hospital after receiving a left ventricular heart pump and as soon as he came home (she rarely visited) she started kicking stuff around asking where were we supposed to "put all this ..... he shouldn't be here...needs to go back to rehab.... let him out too early etc." So, since she didn't want him there, she made sure that he became so ill that he couldn't stay.
I am so angry at her. The only thing that has stopped me from punching her, trashing her car and many other evil things is that I know she would say she was injured, whether she was or not and sue us. I know I need to forgive her one day for my sake but I am not even trying now because I know the pain is still too much. But I want revenge and I want to intimidate her enough so she will stop interfering with our lives without getting thrown in jail.

Any great ideas?

I would go talk to adult protective services now, or the police. The problem is, if the hospital felt he was being mistreated they may have been legally bound to report it. If they didn't you may not have sufficient proof.

You may need t get a lawyer to protect yourself from this person.

I would suggest some counseling for yourself, to start with. You have a lot of anger. And while it sounds like you have every right to be angry, you need to learn positive ways to work through it and start healing. I totally understand wanting revenge. But that's not right. You even said yourself that you know you need to forgive her for your own sake and a counselor could help you move towards that place.
Now how exactly is she harassing you? Do you have proof? I would say get your own restraining order against her. Let her tell people whatever she wants. You can't control what she says. You know what's true and that's what's most important.
