This is mostly new-age Law of Attraction stuff, which kinda gets it right, but people peddling this “raise your vibration” thing seem to take away a warped interpretation of it.
Sound is a kind of vibration, and hearing is the ability to interpret those vibrations as speech or music or noise. What you’re aiming for instead of just “raising your vibrations” in general, is generating the right kind of energetic/mental/psychic (whatever you want to call it) vibrations, in a way that makes them interpretable (on a subconscious level) to your ex, or in a more precise sense, to your own subconscious, which affects the wider One consciousness, which includes your ex.
So for this you can use spells/rituals, or the Law of Assumption/Belief/Consciousness (Joseph Murphy or Neville Goddard style).
Or take a look at this thread and use its technique:
Having “high vibrations”, i.e. feeling happy and in a good mood all the time, is nice to have, but it’s not strictly necessary to get results, and it also has the risk of you inadvertently sabotaging yourself if you start to worry that having a bad day or a bad mood is “lowering your vibrations” and affecting your working. You don’t need to be happy and cheerful every waking minute to have successful outcomes.
Also note that it takes commitment and perseverance. There’s a few things you can do as well, like:
- Stop replaying the old story in your head
- Stop having mental arguments with your ex
- If you find yourself having negative thoughts, firmly remind yourself “no, that’s not true” and replace the thought with something like “how was it so easy for me to get my ex back?” or “why does [ex’s name] love me so much?” or “why is my relationship with [ex] so perfect?”
Again, it takes commitment and persistence, it’s not something you can learn overnight.
