When deep inside your heart, you feel no doubts about your love for the person. When they apologize for doing wrong and you feel like they shouldn't 'cos you never saw it so wrong. When you have all you want to be happy and yet their absence still cause you to feel like you have nothing. When your heart is ever ready to welcome their mistakes, accept them for what others reject them for and ready to work hard to make them happy for the rest of their lives.
The feeling is usually deeper than words can express, but when you have it, you'll feel it and know what is...that it is LOVE.
