key to good and fulfiling relationships ?

I think communication is a important tool but I think that each person knowing who they are and what they want BEFORE they enter into a relationship will help it last longer. That way each person can maximize their own potential and the 2 of them can still create something great when they come together!

It could be communication (openness in different aspects of life) and trust!

I think happy, happy can give you everything.he he ,thanks.
