You only live once. When you get knocked down or disappointed, get up & try again. Hope & pray this time I will get it right. A happy life & love is an amazing feeling. Don't let someone rob you of that. If they do then they surely win!
You don't need another human being to make your life complete, but let's be honest, having your wounds kissed by someone who doesn't see them as disasters in your soul but cracks to put their love into is the most calming thing in this world.
