It's bad to be bitter about a breakup. Here's why.
Suffering is caused by your mind attaching itself to the story you have told yourself. If you keep holding onto the bitterness, the story will ensue and so will your obsession. Instead, change your story. Give it a positive meaning so you can shorten and reduce your suffering.
4. It will be more difficult to attract a new relationship. If you hold onto bitterness, it will be more difficult to attract a new relationship because the attachment to your ex blocks the energy of receiving someone new into your life.
Holding onto the past is like buying new clothes and not being able to fit them in your closet because all your old clothes take up all the room. The only way to fit the new clothes in the wardrobe is to clear out the old. The same is true for letting in a new relationship. So, let go and make way for the new.
5. You will ruin your next relationship. Without healing the wounds of the past, you will be more likely to carry your negative feelings into your next relationship. It will also make it more challenging to receive love from your new partner because you are still protecting yourself from the past.
