Zanna Blaise has a book called the Angels of Love and within it there is a ritual for the Blossoming of Love. It causes your love to reach its absolute maximum, and will decrease feelers if the person isn’t right for you. (She uses the term soul mate, I prefer soul mate type or soul mate type of match myself)
Shit works too, but doesn’t make them act upon it, just makes you both feel it if you should be together.
If you hit the search bar for love spells or love rituals there’s shit tons of information and if you want to essentially dominate how she feels for you… you could try this one, but if she has no feels you’d have to repeat it on a semi regular basis until she developed them.
Might also consider changing your user names if they look like this one, and passwords if they are also in similar line as people tend to draw to them things like that when, they use it and own it as their own/ a representation of themselves.
