I personally think Why relationships and marriages fail in western world is because they prefer the imaginary idea enshrined in them by default to make them dream on and on for instance everyone dream of that Prince Charming,also that amazing chemistry on first date,that captivating love at first sight/wink etc. truth is opposite of our expectations to explain further on that i mean the unexpected aspect of it all is what makes it amazing cuz everything is meant to happen in the emptiness of our soul and if you are lucky enough to experience this only YOU would understand the concept of true love.
