How do I deal with the pain of abuse and betrayal from a husband who professed to be Christian?

While dating my husband did everything which made me believe he was a dedicated Christian--we went to church together, did devotions and bible study. Shortly after marrying him I found out he was not who he portrayed himeself to be. There has been physical,emotional and verbal abuse. I'm separated from him now but feel tremendous pain that he could deceive me this way and still blame me for the marriage breakdown. He is still trying to control as we deal with lawyers and trying to make me look bad in the eyes of friends. I can't help asking God "how much longer"? Any advise?
