I encourage you to close relationships respectfully and conclusively, no matter how short they have been. It acts with kindness and integrity. This allows both people to enter into their next relationship with more experience and a clear mind instead of being filled with insecurity and disappointment.
Here are some of the ideas a person would appreciate to hear at the end of the last conversation:
Thank you for what we have experienced together.
Here’s what I learned from you.
Here’s what I’d like you to learn from me.
Here’s what I want for the future.
Of course, couples dancing in the area of stable ambiguity do not always end up with a breakup. Sometimes, this stage may be the trial period in which one or both partners realize that they want more. It is normal for a short start-up period, but not as a defining state for a relationship.
