A lot of what help you deal with the emotions is time. I tried to read several self-help books but I just wasn't "there" yet. Sorry I don't know much about your situation. Was the affair going on for a year? Why did he tell you? Are you taking AD medication? Going to counseling?
Posting and talking it all out helped me. My marriage did not survive as he still continues the affair with this woman. The only thing about him that concerns me is the kids and how he pushes for their relationship with OW.
Keep posting and I will try to help if I can.
