I think you are right to stay out of her way. She won't listen to you now, and maybe never will. Then again, she might change course at some point. You just don't know what will happen until it does. In the meantime, keep on living for yourself. She's in no place to be of much help to you right now. And if she truly wants to be free, then you have to let her go. It will then be her kettle of fish whether she realizes one day she made a mistake or is truly happier without you. We don't get to decide that. We think we'd like to make a real effort with them, but at some point one person cannot DB. At some point, it takes two to work on a marriage. We couldn't force them to marry us, and we can't force them to stay. Sometimes love does mean letting go, as hard as that is to do.
