If she’s human it’s easy to force through such barriers, they’re better for ghosts and astral entities that don’t have the advantage of the physical body generating powerful.
Make your own wards and also set personal shields, ones you can feel and maintain yourself. - but in this case make them complex, confusing, interesting and distracting, add decoy thoughtforms that look like you to lure her to where you’re not and feed her misinformation. (She won’t force her way past wards she doesn’t know she’s being blocked by)
After that, set a binding on her to stop her from even wanting to have anything to do with you.
