i believe that it is better to go unmarried rather then force compatibilities that are not there. Perhaps this is becoming more and more the life style of the future. Many people 'force' relationships by cutting others out of their lives and then fortify themselves into relationships that really do not speak for their individual spiritual and social values. Nor do they support them. All in the name of a worn out custom that really is not necessary; marriage. At least not necessary until it flows comfortably with out interfering with lifestyle and spiritual seeking.
In the case where someone does have a marriage that no longer fits them... a creative approach must be found to their relationship otherwise they find themselves in a self made prison. It is often better for people to be able to explore the vast potential of relationships and friendships. Through these encounters; there is a wonder that expands our perspective on life rather than a suffocation in narrow confining relationship that do not reflect our growing awareness and expanding consciousness. This includes relationships that may not be marriage but confine us with conditions.

Everything is energy. People carry an energy. If they do not carry an energy that is conscious of spirit then their vibration is animal in nature. If there is no acknowledgement of spirituality then their vibration is dark and leads us towards maya.
We may be attracted to various dark energies as a result of desire, envy, greed or passion nevertheless the energy leads us away from divine magnetism and understanding and on a spiral downward. Magnetism, like most other energy sources is subject to duality and has a dark side as well. People we meet and situations we are exposed to are a result of past karma. However we do have the free choice to discern the nature of our relationships and where we want to invest our energy.
