What is a healthy relationship?

Well, a healthy relationship in my opinion is when you and your partner are emotionally interdependent not codependent. There is no "score card" being kept on all past mistakes and constantly being brought up. Communication is good, there is no covert nudging where the partner has to try to mind read instead of it being stated outright. When simple complaint or criticism doesn't turn into blackmail. No blaming of emotions and no jealousy nor buying things to solve relationship problems. Healthy relationships are built on respect, trust, good communication of feelings and emotions and love not only for the other person but also for yourself. Both parties should be willing to change, recognize lack of affection/trust/respect and be willing to work on it.
