This is the beginning of a new life, out with the old in with the new. take off somewhere if you can affort it and get in touch with the inner you. Re-invente yourself. do something crazy you never dare to do, get out of your comfort zone. Your world has turned inside out, it has been destroyed, rebuilt it, remake it your way, not his or the hussy he left you for. Screw them both, I'm my own boss, ymy own individual person, I'm not dependent on him. I'm a unique creature, beautifull inside and out, biterness does not become me. I let you finish this, you have some many quality in you, you dont even know about here is the time to find each one of them and apply them to your own happiness, you make yourself happy, your husband was not the source of that happiness, I know if hurt like hell, carving yourself with a knife would be less painfull, and the betrayal on top of that. but you know what, that's OK. What come around, goes around, your reap what you sow.
You get back what you give. The world is round, you do soon or later make a full circle.
