Any seasoned military wives out there?

My boyfriend left for basic about 3 weeks ago. We have been together about a year and a half. And we've been friends for about 4 years. I miss him a lot, every time something something bad or good happens I find he is the first person I wish I could talk to about it but I find I fuction just fine with our him. In not overwhelmingly upset all the time. I've had moments but they pass.  I'm proud of him for signing up and I think it will make him very happy and that is all I need to be happy with his choice to enlist. Also I love him very much it's not like I want to be with anyone else ever but I'm not devastated that he isn't here. All the other wives and girlfriends seem so upset and they talk about crying because thier husbands are gone and how this one didn't get out of bed today and that one cried at work. I feel like I'm not reacting right or something. I'm not depressed, I cry when he calls after I hang up because I miss him but after a few minutes I get up and move on. I guess what I'm trying to say is, is how I'm reacting okay? Do I seem like I don't care? I hope how I'm explaining it makes sense. Thank you in advance for any responses.
