Your W left you b/c of how she feels. She was fed up with you and the MR. According to previous information you have given us, she is filled with a lot of anger and doesn't want you talking about anything other than the kids. IMHO, that's a clear indication that your love & commitment is not the issue that is preventing reconciliation. You seem to believe you can change her mind by talking about the relationship. She has told you she does not want it. Even after you heard she cheated, you want to discuss it. Let me tell you something, and please listen. If your W left you for any other reason than healing and working toward reconciliation.........then she sees her business as private. In other words, she doesn't believe you have any right to say something about her seeing OM. That is the thinking of modern women these days. She won't be impressed by your threats. Neither will she be impressed if you endure her affairs.
