Just wanted to let you know I'm following this thread and finding it very helpful. Thanks for sharing your experience. I also don't want xBF to think that I'll just sit around waiting for him to come to his senses. But I also told him I would never do to him what he's doing to me (cheating) so I want to hold onto the moral high ground. Think I will go the mysterious route and let him draw his own conclusions if his mind goes there.
I totally understand why you made up "OM" in the first place, and also understand why you felt you had to come clean. I applaud your efforts to save your M. Keep up the good work.
If you love somebody, set them free. http://tinyurl.com/2empx2g
