I've experienced true love only twice and let it slip through my hands both times. Will I ever find it again?

When you know that most of the failed relationship that you had before was because of your own mistake, it is a good point because your realized your own mistake and it will be easier to fix it. Take time to heal your self first, find a way to handle your self problems, find a happiness and a balance in your self and in your life. Then when it's done, surprisingly you will be more confident, happy, relax, and you can start to show the new you out there, automatically you will attract women with your positive energy. Keep trying and believe that if one star stop shining, you could still find other star on the sky. Good luck ^_^
