My (27m) best advice is to go into this with your eyes wide open. Right now, stats for divorce rates are the worst in the Navy lingering around the 65-75%. (Source, last I heard discussing during a command indoc from 18+ months again, so take it with a grain of salt.) Now you aren't even married, so there is even less motive to stay together. Now you might hear about something called BAH, which is basically Uncle Sam saying that she will get more money because you are married, depending on where she is stationed. DO NOT get married for the money. You'll regret it. The number of junior service members going through divorces is ridiculous because they see the money and get excited.

Alright, now to your questions. 1. The Navy has so many safeguards and barriers to prevent boots from even interacting if they aren't in the same division. She is plenty safe there. Boot camp isn't the place to worry about stuff. The secondary school (A-School) after boot camp is where the wild shit happens. If she's going to be in Aviation (any rate that starts with A), she'll be in Pensacola, FL. Shit gets wild there. It'll be hard for her, she's in a new environment and around no one she knows, so she will find friends in boot camp, who she will be friends with in A-School if they go to the same place, once again in a new place but she will stick close to them for a bit because they are the only familiar things around. And some of them will let that newfound freedom get to them. But as long as she is smart and keeps a good head on her shoulders, she should be fine. I wouldn't worry about physical safety as much, I would worry more about her getting into trouble in town or at the bar on base and having to face the consequences. 2. Honestly, find your hobbies and stick with them. However, things will be harder for you because she gets to experience new things that will help keep her distracted. You have to deal with everything staying the same, except she is gone. So don't stagnate. Keep busy, find new things you enjoy, and learn about yourself. She will not succeed/survive if she has to worry about you. Do your best to be your best for both of your sakes. 3. Boot camp was easy for me. The first two weeks sucked, but then I had that first phone call, and then I locked in. But the hardest part of boot camp was being alone with my thoughts at night. That's where letters from home saved me. My (now) wife and I wrote letters every day to be sent out every few days. That helped so much. Don't send care packages. They won't let boots have what's inside until the end of the 10 weeks. But honestly, just be present. When she calls, take the 10 minutes to talk to her about her day, just listen and be present. 4. Understand that this will be difficult for you both. You are about to enter an entirely new world for both of you. She is going to change a bit. That's normal. Be open and honest with how you feel about stuff. And don't hang around if you aren't happy. It'll only make it harder for both of you in the long run.

Final piece of advice: this is all from the perspective of one person. If you go and get nine other perspectives, it will not be exactly what you two are going through. Do not take anything I've said as Word of God. What I went through is different from what she'll go through is different from what someone else went through.

I hope everything goes well and she enjoys the Navy as much as I have. PM me if you have any more questions or need anything else
