I'm sorry for the pain you are in! I suggest you channel it into yourself by going to the gym and making yourself look fantastic! It is such a release to beat your body into shape at the gym. It produces endorphins that clear your mind and make you feel more positive. There's also a great side effect- you will start to look like a very hot you! Everyone will notice- including your husband!
That brings me to my next point- become attractive to your husband. Change your hair style - drastically (whatever style is hip and hot). Wear more revealing clothes no matter where you are going. Wear nice undergarments. FEEL good about how you look in the mirror. When you feel good, you will project confidence and be more attractive. Don't get baited into arguments with your H, dodge them. Only use kind words (even though it's hard!). Become a women that other men notice. Believe me, as much as your H will try to pretend he doesn't see the changes, he will start becoming attracted to this mysterious new woman.
As long as you are acting unattractive (name calling, depressed, etc.) he will (surprise! ) find you unattractive! Only do things that put you in the best light possible. Become a woman that men scrabble for, not leave.
