WHAT IS LOVE,if its there then why does divorce happens, why breakups?

because different people have different ideas about love, relationships, and marriage. Some people are hasty and some are needy. Whatever the cause the love leaks out of the relationship because someone is not getting what they need emotionally or spiritually or in moral support and they think that something new and exiting will fix the problems within them. And so they move from relationship to relationship. I've known people who have been married 5 or more times.

This is a very complex question. I don't know whether I am qualified to answer your concerns, but I will tell you what I have observed about this. The more you love a person, the more there is a chance for hurt. There can be needless possessiveness, doubt, and unwelcome levels of freedom...Love is not something which is permanent. It keeps changing its shades. The moment you realise that the magic is over, it is better not to stick around for long, to aggravate the painful factors, or to hurt yourself. If we get rid of the idea that the ones we love hold a life-long allegience to us, it's all the more better. I am researching on an alternative way of human contact, which is used just for procreation, devoid of any kind of emotional attachment, like what we find in SF novels. You see, we will be able to save a lot of our time if get rid of this falling in and out of relationships!
