While they understand that relationships require a balance of healthy give and take, they don't associate their worthiness with how much they can do for the other person. They understand that dating is about expressing themselves and looking for alignment, it is not about impressing people.
Instead of stepping into the dating realm trying to get chosen by anyone who reciprocates interest, they place high value on themselves and look for a truly worthwhile partner. Instead of asking, "Am I good enough for them?" They ask, "Is this person good enough for me, my life and my well-being?"
They are okay with losing dating prospects, they aren't okay with losing themselves. They don't run away at the first sign of discomfort but if the other person's pattern continues harming their well-being, they are not afraid to walk away. Their desire for finding the right relationship is much greater than their desperation to keep just about any relationship.
