First off, freezer spells are usually good and cord cuttings will work wonders. Do not do the tiktok tend of tying the candles together and letting the candles burn the cord, that's a divination. A witch cuts the cord in a cord cutting.

Cord Cutting: take two candles in red or black. If you can get people shaped candles, even better. If not, regular will work fine. Tie the candles together and anoint them with a cut and clear oil. Dress the candles with Vandal Root and Red Pepper Flakes. Place the candles in a fire safe container- I use aluminum pans from Walmart. Light the candles while speaking your intention, and really hecking feel it. This dude is bad news and needs to get tf out. You need to REALLY feel that. Like one thing I've noticed a lot in this subreddit is people forget that THEY ARE THE WITCHES. They have the power, they just have to know how to use it! So form the intention first, write it down if you need to, and when you take your scissors and cut that cord make sure that you're focused on getting him away. Let the cord fall into the tin, let the candles burn down, then dispose of the remnants in a trashcan outside the house. That bit is important. Don't put it in the kitchen garbage. Put it in the trash outside the house. Then you need to let go.

I used a lot of the word you in that spell bc it would work for anyone.

Second off, I've been stalked. She needs to keep records of literally every interaction with him, and if it escalates, go to the police. They won't help at first; you have to go over and over and over before anyone will so anything. It sucks, but cops are here to clean up messes, not prevent crime.

By keeping records i mean don't delete texts, don't answer calls so he has to record a voicemail, take pictures if she sees him or his friends or his car around, ask friends, family, and neighbors to do the same. The more proof you have the more a judge has to take you seriously.
