Wife admitted affair, I want to win her back! How?

My wife of 18 years admitted to me she had an affair with a co-worker three months ago. At that time she said she needed space to figure out things because she wasn't "in love with me". So I gave her the space, she moved out and we did that for about a month. She also said he was going to tell his wife too. After she moves back in I find out he did not want his wife to know, but continued to see my wife in her hotel room. I confronted her about this and she admitted that it was the truth and his wife could never find out. I did not like this because I had a feeling he was telling her things she wanted to hear and in return he got what he wanted. Anyway I debated for a week off and on about contacting his wife. Eventually, not out malice, but of love and wanting my wife back I contacted her by dropping off a letter in the mailbox. The next morning my wife called me crying saying she found out about him. He called her and told her that nothing he said about them moving forward was true. She was just putty in her hands and he got what he desired. Basically she was a piece of ass. She was upset he didn't want anything of her and she wouldn't see him again. So now we are here three months since she told me and I'm not seeing any progress. What do I do next to move forward into her wanting to work on us? Posted via Mobile Device
