Is this really how it supposed to work? If either party made a mistake, are you supposed to punish them?

Can anyone tell me what is the definition of a healthy relationship?

Changes, is it supposed to be taught by someone, or taught by situations?

Do you accept the person you knew from the beginning and let them change through process and nature or do you groom them to become better so they know how to deal with society?

Society or is the person who walks the journey with you?

What's the answer? Or is there any answer?
