If you can’t love her with all you got, please let her go. You need to be the one thing in her life that’s always there, the constant. There’ll be days when she needs you there at 3 in the morning telling her she’ll be okay and that there’s nothing to worry about. Your arms should be her home and ONLY for her. Your smile should be her heaven on earth. Please love her for all she is, even if she has scars from the past she can never get along with.
But if you can’t do all this for your girl, please don’t waste her time. You need to be the person to kindle her spark, not dim her lights.
