This is happening in every relationship. Instead of recognizing that someone is fulfilling your needs, you think you are doing a great job for them. When something goes wrong somewhere, you think, “He is responsible.” The moment you point your finger towards someone, this is the beginning of a bad relationship.
Relationships are about people. Different relationships need to be conducted in different ways. But love is not about someone. It is not relation-specific. You could simply be loving with just about anything, and that is how you should be with the whole existence.
