I think there's definitely an "actual mileage may vary" caveat to the one month for every year theory. I think there's probably also a minumum length of marriage for it to be valid.

My wife and I were married 18 months before she moved out, so we're coming up on the month and a half point and no change really in sight. I guess you could include our time together before marriage, it would be two and a half years, so 10 weeks. Maybe I can reassess it then. But I do have a couple 'real world' friends I've been confiding in who have suggested she may have to be 'all the way out' - ie, dissolution finalized and all that, before she can consider a reconciliation. I think there may be something to that in my case.
