Hi Miss_A,
I have moved your post to the correct thread on troublesome family members, as this is the more appropriate location for your situation.
I am sorry you are having so many difficulties with this woman.
21 Divisiones is a Dominican spiritual practice and we cannot speak to that here, as this is a forum for the practice of hoodoo. However, you can employ several hoodoo spells to get her to back off.
You should put her in a mirror box, to return her evil back to her. Do a little search of the forum for mirror boxes and you will find great advice on how to construct one for her.
You have done a cleansing bath, which is great, but you have not talked about doing a cleansing of your home. Use Chinese Wash for this, and it can clear away any spiritual gunk that is lingering in your home.

Search the forum for Reconciliation advice and you will find a lot of very useful information.
If you do wish to appeal to a particular saint, Saint Martha the Dominator has been very helpful in subduing misbehaving men. Her thread is here:

And products to work with her are here:

I hope this helps. Good luck.
