Upasaka Karl mentioned in an answer:
Relationships have a beginning. And because they have a beginning, they also have an end. Thoughtless endings, ghosting and worse, hurt both parties. It is sad to treat each other like an Amazon shopping experience. We become each other's dismissable clickbait. Yet perhaps a thoughtless ending was matched by a thoughtless beginning. Perhaps we can consider and nurture relationships that matter.
Isn't it merely the case that personal relationships never really end, that some of the debts remain forever? That one actually stays bonded forever, even after ending of a relationship...
What are the valid reasons for ending a personal relationship?
How to end a relationship properly?
Which (as it were) "relationship" can't be ended, once gotten into?
What's the effect of denying being in a personal relationship and consuming outside of it, thinking "I am free" or "this is my right"?
