I think this means you do not love just because. You love because you feel the connection and passion between you and your soul mate. You love because you care. There is a lot more to love than just "love" in bed so to speak.
What is love? Love to me has many different definitions. Love is waking up to your soul mate in bed. Just watching him sleep peacefully and wondering what he is dreaming about. Love is having your soul mate trying to anything and everything to help you get over your cold by treating you like a princess. Love is knowing that God gave you another day to live life to the fullest. Love is still caring for your sister even though she makes mad. Love is just giving a smile to everyone you see. It could really change someones day. Love is coming home to your dog and just seeing how excited she is to see you. Love is comforting someone through a time of loss of a loved one. Love is giving back to those who have less than you do. Love is taking time out of your busy live style to help someone who can no longer get up and move like we can. Love is your mother, who is single and raising you and your sister, and helps you pay for college even though money is tight.
As you can see love can be many things. Your love grows as you get older and start to have children. Just remember that you do not love just because. You love because you chose too. So what does love mean to you?
