As someone in a similar position I know what you're dealing with and you are not alone. It is hard especially when your loved one will go on leave and then take off again, sometimes for a long length of time. Don't worry about him not missing you because trust me, he will. Contact him via whatever is appropriate as much as you two can. Those are the moments he will love. A true warrior wife (or girlfriend) stands by his side, even if it is at a distance through it all. That is what he needs from you is support and love which I am sure you won't have a problem with. It is okay to miss him a lot, I've cried too but stay strong and be there when he is able to come home. It is an adjustment but it will get better and you'll learn how to cope/communicate with this new lifestyle that he has pursued that is best fitted for you both. And if it helps you, do research on the training at TBS and other things he does.

My boyfriend left for PI, SC the other day. We were inseparable, i'm not going to lie. Being a Marine girlfriend is not always going to be easy. When he leaves, just keep yourself busy, and don't sit around the house and feel sorry for yourself! This is what HE wanted with his life! You just have to keep moving forward with you life, I know it sounds really scary and hard to do. It is what you should do though! Your going to have your good days, and your bad days. He will always be thinking of you, he is going to be worrying about what your doing, so stay as busy as you can! these 3 months are going to fly! He will have one hour a night to write letters, you wont be able to talk on the phone with him though, the letters are as much communication as you are going to get from him. He will come home for 10 days after boot camp, after boot camp, he is allowed to have a phone, computer and all of those good things! Hope this helps!!!
