WAIT. I absolutely feel entitled to other people's time and energy. That's how relationships work! Relationships are defined by how you treat one another. That includes how you treat one another when it's time for the relationship to end.

If one person decides to end the relationship, great! Say so. Trust the other person to not lose their temper or their poise. Treat the relationship with the modicum of respect that you would treat any other relationship, including a business partnership.

If you fire someone, you tell them they are fired. You might give them the opportunity to talk to HR about their feelings. You offer their final paycheck.

Personal relationships, especially long-term relationships, deserve the same consideration.
