I see when men love women. They give them but a little of their lives. But women when they love give everything.

This quote means that when a man loves a woman, he may not dedicate all of his time and energy to her. He may still spend time working or with friends and family, but may not show all of himself to his partner. When a woman loves someone, however, she may give up nearly everything to be with the person she loves and show her love in the most meaningful way possible.
