I really think any contact with the OM is inappropriate for either LFL or her H. He has no part in the drama. You can't blame him for checking with LFL to see if she is interested/available. He did nothing wrong in contacting her. At the time he was with her, she was not with her H. He really isn't the OM-- he's just a guy she saw while she was separated. He doesn't need to be "chased off." You can't blame a guy for trying-- he doesn't know if she's still married or not. No one owes him any explanation or information. I certainly can't see what would be served by LFL's H getting into the act.
