Karl I found this for you
To get someone to stop harassing you, you can start with a cease and desist harassment letter.

If you are not in immediate danger, send the person a cease and desist letter and keep copies for yourself. How do you stop harassing texts and calls? It starts with a cease and desist letter. How do you stop someone from harassing you on social media? The same. This letter is a powerful tool, and it may stop harassment.

Telling your harasser to stop, in writing, creates an official record of you saying “no.” While this letter is not legally enforceable, it is clear evidence that you have rejected your harasser’s actions, — which you may need later.

Keep records of harassment.
You need to build your legal case. Start a log or notebook where you write every incident of harassment and contact with its date and time. Do this as soon after the event as you can. Having clear evidence helps stop the harassment.

Keep all of your texts and emails. Photos and screenshots are also good evidence. Recordings, like messages left on your answering machine, are also evidence. If the harassment occurs in front of other people, record their names and phone numbers. You may need them to be witnesses later or to sign an affidavit of what they witnessed.

Then you would have to file a restraining order

Just type in : Example cease and desist letter and you can find one to use but be sure and date and keep a copy.
Hugs and good luck to you and your wife

Start documenting all her communication attempts, and let her know that you're willing to file harassment charges against her if she doesn't stop.

Let the police come repeatedly if necessary, and document those visits as well, and tell them that you're prepared to file charges against her if she doesn't stop.

Look up the harassment laws in your state, so that you can back up your threats. I've had to do this. It's an effective means of getting controlling people to back off.

Also, take a look at Bpdfamily.com, and look for the term "greyrocking." And of course, block her on social media altogether.

Good luck, Karl. ❤️‍🔥

Run Forrest run😛😝🤪

I have a feeling you can block a number on your phone. I hope things work out.

Umm this may sound unhelpful but if you figure it out let me know
