LPT: Use ChatGPT to help you take them off the pedestal.

If you're having trouble taking your ex off the pedestal, or if you're just falling back into a nostalgia trap, like I have recently--tell ChatGPT a summary of your relationship, and allow yourself to fully vent about all the bullshit they put you through. All they ways they let you down and hurt you. Then ask it to tell you why you don't want that person in your life anymore, and it'll give you a very helpful summation of why that person fucking suuuuuuuuuuucks.
