1. Respect
2. Trust

Those are in no particular order but those are seven things in MY opinion that create a good relationship. Life is too precious and too short to continuously put energy, time and emotions into someone who does not even give you the time of day, so-to-speak. This can include friends, significant others, family, co-workers, anyone really.
I have always loved the saying "ACTIONS SPEAK LOUDER THAN WORDS". I believe that will forever stay true, of course not in all situations, but in most.
