The best relationship advice I can give you is to understand what relationships are, and how they work.
Any relationship is the sum total of what each party brings to the relationship. First you need to know what is important to you in any relationship. Why does this relationship exist and is it fulfilling? If not, why not?
The most valuable relationship advice is to understand that the most important relationship in your life is your relationship with yourself. Do you love yourself? Until you learn to love yourself you will not be able to have a fulfilling love relationship. Learning to love you begins with getting to know yourself. Who are you? You may answer by giving your occupation, your philosophy, your role in a relationship, but all of those things are just things about you. They are not who you are.
In order to discover who we are on a deeper level and truly experience love you must take some time to go within and discover yourself. Most people in the world today are severely over stressed and when we are over stressed we are unable to really feel love or know love. When we think that love is something that someone else can give us, we continually look outside ourselves for the love that can only be found within us.
When we believe that love depends on someone else we are always kept in bondage. When we know that we are expressions of love, and that love comes from within ourselves, we are then able to share the love that we are with others, but until we discover the love within ourselves, no amount of relationship advice can help you build a fulfilling relationship.
In my book Unlimited Futures: How to Understand the Life You Have and Create the Life You Want, I explain the origin of love, and I give you step-by-step guidelines for what you need to do to create the best relationships possible for yourself.
