There are many reasons people enter into relationships, just as there are many reasons why relationships fail. Many of us were brought up to believe in the fairy-tale kind of true love, and that it is the key ingredient needed for a relationship to last.

In hindsight, we eventually realize that love simply isn’t enough to keep a relationship going. You need things like respect, compromise, and trust, to name a few, in order to make it last. When one finally realizes and integrates this knowledge, one can enter into a new relationship with a better understanding of what it takes to make it last.

Healthy, happy relationships are built on trust, freedom, compromise, compassion, empathy, and respect. Once those foundations are set in place and solid, love will naturally sit on top. The goal is to feel emotionally and spiritually sound within a loving relationship.

Here are 11 rules happy couples regularly follow, according to psychology:

1. Love and respect each other

There will never be room to question the love or respect factor; it will come naturally, and so you will undoubtedly feel safe and secure in that love. Research has shown that feeling loved and respected by a partner is significantly associated with higher relationship satisfaction.

Love motivates open communication, and respect ensures that communication happens within a structure of understanding and consideration. This is even more important during disagreements.
