Relationships end for a reason. When you breakup it’s important to always remember why you broke up. It’s easy to only remember the good parts and that is often how people get sucked back in again to the same relationships and the same kinds of people.

Keep remembering what the breaking point was and how you felt at the worst times. Doing that makes it easier for yourself to rationalise why you are not together.

Also total separation is key. No willing contact again ever. If they are gone completely, then it will be easier to move on.
