I dont think it work like that, sounds a bit new agey. Of course your vibrational frequency could play a indirect role.
If you want to try it out, you could implement techniques described in this thread, at the bottom is the updated version.
You can also always try this method: By using the demonic language.
Although you mentioned having the desire to manifesting your ex back. (or induce love) You could try the incantation of creating sexual opportunities. As one thing led to another
It is wise before using the demonic language to first attune your throat chakra as it will potentiate your further chanting’s with the demonic incantations. If you have trouble to identify the proper pronunciation.
I can send you a link in which the person who channeled the incantations speaks them.
