Advice-Husband moved in with OW(I'm a Newby)

[Trying2live]

This is my very 1st time on a forum ever so forgive me in advance if I have posted in the wrong category. Please offer advice if your are able. He's moved in with her and I just need some advice.

Found out my husband of almost 19 years had an affair on April 23rd, 2008 about 4 months ago. He exposed to me and children. I have been with him since we were in the 8th grade. I am filled with sorrow. He is no longer recognizable as crazy as that sounds. Even his natural reasoning is gone. During a mothers day dinner he wanted me to agree to him living in another residence for 3 days a week saying it was normal and that I'm crazy and black and white. He has blamed it all on me. He drinks a lot now said had to to kill guilt and the more he did the more he wanted her. I am at a loss for words. I never wanted to do anything but be a good wife. After his revealing he was home for 2 weeks. He was very angry and I suspected sometime during the 2 weeks he went back to her. I asked him if he did and he kept saying no. I had hired someone to take pictures to prove it and sent it to him email. He then confessed he went back to her. He has been out of the home for almost 3 months and moved in with the OW on August 1st. I don't ask for much advice from friends or family as most of them have no idea as they have not experienced it. I am trying to educate myself as much as possible I have read Dr. Dobson's Love must be tough, And also read Divorce busters and implemented the last resort. I do not have contact unless absolutely necessary. But now that he has moved in with her I feel insane for even considering reconciliation. I almost could handle the affair if he'd stop lashing out at me via email. Please give me advise on what to do when spouse moves in with OW. Is this hopeless? Sure feels like it.
