Its not your fault...

If someone tells you that you that they love you and want to spend the rest of their life with you, then tells you six months down the road that when they said that, they had doubts in their mind about what they were actually saying WHEN they said it, and then proceed to break up with you...its not your fault. That action, no matter what they try to candy-coat it as, would be called lying, and one can only have so much intuition regarding seeing through a lie when someone is consistently lying to your face and is an apparently excellent actor. :)

God has amazing plans, and although we do not get them when the hurt makes you want to rip out your heart and throw the bloody mess at the one who has wounded you, it IS for the better. You can look at the broken mess that your life is, and realize, "HEY! I can't fix this!" and you let the one who knows how to put it back together again take it up and make it better...the best.
