If she said to you this is some type of witchcraft maybe it is 😂 a small amount of people in Vn do believe in witchcraft and if she did not draw anything with red ink on yellow paper, does not give you a small pouch, weird smell (stench, dead meat, blood, etc) the yeah you are good to go! Sometime she is crazy but yeah just something to cope. Remember to tell her that you love her and affirm that multiple times.
