How does one move past anger?

I am emblazoned with anger and bitterness, and I don't know how to let it go. My husband had a job opportunity a few states away, and sold me on the idea of leaving everything behind. He was offered a partnership in an established business, with a great income. In no particular order, I gave up my career and benefits, my house and many of my possessions, my friends and family, an easy-going lifestyle, and general financial stability. Within months, work dried up, and rather than trying to keep things afloat, his partner bailed. He left us high and dry, and took an executive position elsewhere. I'm angry with my husband, for getting us into this mess. I'm angry at his lousy business partner, who led us into the gaping maw of financial ruin. I'm mad at his twit of a wife, who to this day, spams me with her recipe chain letters. I'm even angry with myself, for trusting my instincts and being fooled. I've lost my sense of trust and optimism in the world. I have been lit with fury for a good six months now. I can't even think about the situation, without breaking out into angry tears. How can I move on?
