From all indications, when two people are in love, what they are fundamentally doing is saying, "I am giving you my heart. Guard it jealously and handle it with care as we take steps towards building this relationship".

Well, these words are pretty common to hear when someone is in love with another. But to tell the truth I don't prefer the words most to express my love to my loved one. I feel someone's acts are more important than the words. When you take care each other rather than enforcing I need the care of your which does not come out most of the cases naturally. If both are honest and loyal to their love, I don't feel they will go for a break up in any sense unless misunderstanding.
