John Lennon who abandoned his first wife and son and cheated on Yoko, albeit with her permission and couldn't get along with Paul.   Fat lot he knew about love.

IMHO, if your religious preference is important to you in general, it will be important in your relationship to your spouse. 

Your relationship with your spouse should be the most important one in your life and if religion is important to the rest of your life, it should also be part of that relationship.  It does not have to be the same preference -- but that would certainly make things easier.  If they are different, each spouse must choose to respect the feelings and experiences the other has had in their religious preference. 

Love, respect, and trust are choices we make in regard to our spouses.  Communication is a skill, it has to be learned.

An immature approach to love will of course be ineffective and by itself only lead to unhappiness.

With a mature approach to love, however, it is indeed "all you need."

Simple - but not easy.

What is described is of course an immature approach to love.  Manipulation has no place in genuine love.

Mature love never says "If you loved me you would..." And in any event, nobody can be manipulated without their consent.

It is true that not all relationships "work" - and that does not alter in any way what is being claimed.

In a committed long-term relationship, "all" that is needed is love - but of course the genuine kind, not the childish kind.

If love were truely for only perfect people, then love would be for no one at all.  Love isn't about being perfect or even perfect for someone.  Its about being you and being content with yourself and the one you love.  Its about knowing that your loved one enjoys his farts more then you enjoy new shoes but being able to laugh it off on the good days and shake your head and tolerate it on the bad ones.
