Navy,
Seriously man you need to put your foot down and let her know you will not be blamed any longer. She has not divorced you, but she has not worked to renewing your marriage either. That in itself is a choice.

You should consider a timeline, and let her know. She won't make a decision because she doesn't have to. Like I said before maybe you can tie it to your PCS. If by the time you PCS she is not ready then you'll leave without her.
