Navy
Your W is depressed and medicating with alcohol. She's in too deep to be objective.

It sounds to me like she is too afraid to make a call. So she is riding out limbo until you make the call for her or until she finishes her degree and is able to be independent from you.

Unless the status quo is ok with you, I recommend you at least start demonstrating to her your frustration.

I believe that at this point in the game she has a compelling reason to stay, but is too stubborn to admit it. I say you ratchet up the pressure.

When is your next PCS?

Maybe you could tell her that she needs to make a decision by the next PCS either love navy or not.

I can see you are hesitant to lose her, she knows this and uses it to walk all over you. Let's face it though in the last year you haven't had a W in your house more like an irritable room mate.

I've been recommending a blog lately, its aimed at helping guys take back their sense of worth in the relationship. Check it out, it's helped me.
