If you don't want to be married anymore, then get a divorce. But the hard date I don't get. I think you are hoping that day becomes and ultimatum and a deadline and she does some 180 at crunch time. But we all know that won't be a real 180. her decision to work on herself will be one she builds up to and happens over time. You don't want her just running back because you put some hardline date on the divorce thing.
