Well, if she won't even respond, maybe you should consider
making things legal in terms of moving on.
I'm with Carl-- if things do sort out between you two, you can always remarry,
rekindle the relationship, but if things are too far over to fix,
you won't be spending another year waiting with no response.
A year is a very reasonable time of sobriety to at least get a response to an email.
I also think Day Trader makes some excellent points--
maybe we addicts expect things to be our way a bit too much and she's not buying that any longer.
Or maybe she's just had enough but not able to articulate or acknowledge it.
