You have had a really rough time. You are doing all the right things. You will definitely know that you have done EVERYTHING to keep the marriage. You will have no regrets and this is so good. Do NOT stop.
Google Retrovaille and you will find the information. I'm not sure how you will get her there either. Her tears makes me think that she is torn. She needs some guidance other than the OM and she doesn't believe she loves you.....if only you could both see a pro-marriage counselor or get to retrovaille.
