Men are weak and jerks! They take the best of us, our best years, our energy from dealing with their BS our looks our health and then selfishly throw years like 33 years away at the moment someone else gives them 5 minutes of attention. So that you have no regrets, FIGHT for your marriage! But don't agonize of his affair! Fight by getting BACK TO YOU! Lose weight! Get lipo if need to and pay for it with his money! Get a trainer, new hair cut and color new outfit and new interest. Get some new friends! All while you are doing this, plan for your divorce! Get your life back and see if he regains interest in you. If he doesn't someone else will and you'll also feel better about yourself! Then graciously accept his desire to leave. Shock him by not adding drama to the situation. Believe me him will be confused seeing this new you and how willing you are to move on! Then he'll want to fight for you! Works almost every time!
