My husband left us to go visit his family, he has 30 days and I want him to split it evenly am I being selfish?

He is in the military and he only has 30 days before going to the dessert for a year and a half, there is a possibility that we can go with him as well, but its not for sure just yet and won't be for sure for at least a couple of months. He went back home to visit his friends and family and does not have a return ticket back home, I told him that it would mean the world to me if he could make it back for the forth or July...this is also before he left that I had asked him, and he kept telling me "maybe" or we'll see. Finally the time has come closer to the 4th and he is telling me that hes thinking about spending the 4th of July with his mom and his sister. His reasoning for that is that he's been with us for a little less than two years and he hasn't seen them in a year and a half. For some reason it broke my heart when he told me this and I cried myself to sleep and was in a slump for over two days. Now that the time has almost come and he still has no ticket back home, hes telling me it would break his sisters heart if he left her and that they haven't spent much time together. I understand that and I'm so sorry he's in this position. He asked me why it was so important for him to be here on the 4th, and that it needed to be special that way he'd have something to say to his mom and sister about coming back home. Am I being selfish? He's told me I am? I won't even be able to spend our first anniversary with him. Any thoughts would be greatly appreciated, I would really like to be put in my place if I'm not in it already...I'm just so confused am I really being selfish? On the 4th it will be exactly 17 days since his vacation started. ( and for those thinking why didn't we go back home with him in the beginning, it was established that it would be a great deal of money for all three of us to go with him hotel, car rental etc..)
