Am I not important enough?

I know that my husband is deployed and I know that he has things going on, what I don't know is why am I not important enough for him to want to talk to when he is able to? Why does he ignore/"forget" things that I say to him? Say for instance, today we did talk for about 5 minutes till he went to chow. Earlier I had sent him an offline message telling him I got the gift he had sent me and was asking if he wanted me to wait till we could talk before I opened it. I know he got it, it shows up that he got it. When we finally were able to talk he never mentioned it. When he said he had to go, I asked him to call me back. His response was "If I can." To which I replied, of course you can then he snapped at me "Did you forget I am in a combat zone?"

No, I have not forgotten that, I am not an idiot. But I also know that he was going to chow and then to work out, not on a mission. I also know that at 1p.m. my time he was online and never bothered to say a word to me. Fine, if he does not want to talk to me then I will not force him to. His gift will sit there, unopened and I guess when he finally wants to talk I may by then want to talk to him.

I am angry and hurt and he just does not care.
