I have so far maintained a positive karma to post ratio...until now

First... Thank you for your service.
Second...Thank you for not being old enough to have joined while I had to run a division. You seem very codependent and your new bride seems very high maintenance. Or perhaps, you just don't trust her enough to be away from her. Being away for 6+ months at a time has caused many a set of knees to "go bad" or backs to be "wrenched". Then, when you are gone, the division suffers because of the lead time it takes to replace you.
I deduce by your posts that you have lived in a bubble or do not get TV out in your part of Texas. I have seen countless stories about deployments that have been extended and the families that have had to improvise without the head of the household there to fix the leaky faucet, change the tire, change out the AC filters, get the car's oil changed, watch the birth, be there for the conception, etc. Are you and your honey truly aware of the sacrifices involved?
Very few enjoy being away from their spouses. Fewer enjoy the mail calls that seem to come without letters from home, when there should be letters and everyone else got several. Only later do you find that the bag with your 8 letters is still on the carrier or got moved ahead to wait at your next destination for liberty. But you find that out after you sent a scathing letter home asking

?
The Navy is no place for someone who cannot live without their significant other attached at the hip...it will either get you hurt or killed, put you in a position to damage equipment, or a Bad Conduct Discharge.
If I have read you wrong and misunderstood your intentions when you say that you won't do your job if your wife isn't there to greet you when you get home:
You should immediately connect her with a support group.
You should immediately connect with a support group. I would recommend the Chaplain, but the one on my first ship told me it was his "main job to keep families together and to teach sailors about forgiveness, because it is only natural after being alone for so long that your wife will cheat on you." Either he was a total butt or he was pragmatic, you decide; however, this is the type of "help" you can look forward to from your buds when you are out to sea for extended periods.
Welcome to the real world.
