Hi Salty, "craving" someone else can be an attempt to recreate a co-dependency, especially if you begin dating while still open to reconciliation, or as soon as you decide not to reconcile. When the Co-Dependency Demon is defeated, one doesn't need another so badly or to complete them. Since I closed the door on reconciliation I've been solo and not dating for 2 months, and I intended to do so for a mother 2 months, to get my baggage in order. 4 months for a 4 year relationship to be ready for what's next.
I can see that as a way to get move from one co-dependency to another. And I should clarify, I am not craving to be with someone else any time soon, but I do crave to be with someone else at some point who treats me how I deserve to be treated.
