Thank you once again everyone

I'm not exactly sure what to do here. Thank you also for the encouragement and pointing out the fact that taking this first step was a good thing.
I guess I could start by saying what happened. I thought all the world was fine and then one day while fixing dinner, a strange man called me and told me my husband was having an affair with his wife. I didn't believe him. I did, however, confront my husband and he denied it. But there were tears in his eyes and I knew he was lying but I didn't want to believe it. He joked about it for two weeks and then I found an email that he printed out from "her". It was all true and my perceived world was turned upside down and suddenly, everything that I thought was real, turned out to be nothing but a lie.
I don't know what to believe anymore. The world is without substance.
Betrayed
