Because they aren't right for you. When you meet the right one, you'll understand why they all left.
If you insist on keeping the wrong ones that hurt you, the right ones will be delayed or denied their rightful place in your life.
When you meet the right one you will finally understand the real intentions of LOVE: to bring peace, unity, love, hope, joy, confidence and other beautiful gifts that gives life satisfaction and fulfillment.
Don't give up waiting for what you believe you deserve. Ihatelove
