@DeanHelms122,
People responding on this thread don't know anything about boot camp. My son went through this as a soldier, and we went through this as a family.
1. Boot camp is really difficult. It is designed to be difficult. Many people wash out, and many of the people who end up making it have to push through questioning their decision all of the way. You need to understand this first of all. Don't demand anything of her, don't ask her to make a decision about anything. Just be there for her and tell her you care, that is all you can do until she gets set up in her new life.
2. Boot camp is followed up by specialty training. From your perspective, this is just more boot camp. It is still really hard.
People here saying it's 10 weeks don't have a clue. Depending on her MOS, it is significantly more than that.
3. During boot camp, the only way to communicate for most of the time is through hand written letters (the kind with an actual stamp on them). Access to a cell phone or email or text messages is rare.
If you haven't sent your girlfriend letters and packages... do so now. That is the only way you have to show you care. My advice, do this now!
4. If you have been dating her for 4 years, hopefully you are on good terms with her family. If you are, offer your support to her family. They can help you understand what is going on.
5. You should do two things right now. First write a letter, by hand, and mail it. The army will always deliver mail. Mail is sacred in the military (the Drill Sergeants aren't allowed to use mail as a punishment).
Second, buy something small, but meaningful to you and her and send it as a package. But, be aware that anything you send in a package is public (everyone can see it) and Drill Instructor are allowed to take it (so make it something that doesn't have much value), and they can use it as a punishment.
A woman sent her boyfriend a pair of her panties while he was in basic training. The drill Instructor took the panties in front of the entire class, and hung them in the common area of the barracks, and they stayed there. After graduation the Sergeant thanked her for the inspiration she provided to every member of her class.... so be careful what you send.
But she will appreciate a package... make it something meaningful, and remember that this isn't the time to be demanding that she make a decision. Just be caring and supportive.
