To Convert 'for' and 'in' Love?

True love is meant to be undconditional, with no restrictions, no expectations. It goes to the extent of not being possessive, jealous of the other and not controlling the other human. It's all about mutual respect, understanding, enjoying and loving the company and presence of the other. Right?

Then why does religion come in to play? Do we love the person for what s/he is? Is it not the soul that matters? Why do some people agree to convert and why do some others expect their so called future better-half to convert?

Why succumb to socitial pressure? Why not respect each other's religion and each other as individuals?

God is after all one(worshipped in different forms) for those who believe in the existence of the supreme-supernatural power. As for atheists it should not make a difference.

Will people ever change? Will the world ever change?
