You are at least six months away from saving your marriage, so try not to get caught up in the day to day stuff of her not contacting you for a few days or her laying into you when she contact you. You'll have your chance to work on things once her anger subsides, and by the time you get home, it will have. Just stay focuses on getting home and doing the best plan A you can in the meantime.

Trust me, if you do eventually divorce, it will because YOU have decided that SHE isn't worth it, and that you are ready to move on. You hold the cards. I bet even if she showed no inclination on working on the marriage after several months of plan A, if you went to plan B/D with her, she would start poking around (he who cares the least in a relationship, holds all the power, and she will notice that power shift and react accordingly).

My WW talked about divorcing me for MONTHS, but the day I had an appointment set up to file for D myself is the day she agreed to NC.
