Here try this to specifically target the unwanted feelings of pain and angst coming from your disappointment with this dude.
It’s a bit of effort and that’s part of why it works really well. Takes about 6 weeks to feel completely free of emotional coercion by the unwanted energy.
At this point, this situation is pretty bad and has been going on for months, and can be thought of as parasitic, feeding itself on your pain to exist. Which means it starts to make everything go wrong to make more food for itself, and can affect new relationships too… Get rid of this all and kill it so you can stop overthinking it and spiraling around this, and go do something productive.
