What does it mean for a man to say that he lacks you in his life?

Men say they like you without you in their lives. It means a way for boys to pursue girls to express their love. Simply put, some boys will say, honey, I have a car, a house and money, but I am missing someone. Please marry me. The symbol of romantic love begins with the lack of you in life. I wish all the boys and girls in love can be happy and work together to create your own future.
