Assignment to Korea

So the other day my hubs calls me and tells me he has an assignment. I am already freaking because our daughter graduates high school next year. Then...he dropped the bomb. The assignment is only for him, he is going to Korea for a year, and he leaves in the next 6 months. I know that I shouldn't complain about this. Lots of spouses have to go through it, matter of fact, I have a dear friend that is going through it right now. However, my husband has barely been home at all since we were stationed here. He has missed holidays, important birthdays (Sweet Sixteen), school programs and special days, entire summers, and many milestones. I have lived here for 2 years, and he has maybe been present for 1/4 of that! It sucks! Our littlest daughter is totally attached to him, and is going to be devastated that he has to leave for a WHOLE YEAR!!!! He will miss our oldest's high school graduation! It just is not right. He is my best friend and I cannot imagine a whole year without him. People keep telling me that I will get through it, and that I am one of the strongest women they know, but you know what? I DON"T WANT TO BE STRONG!!!! I want to scream, cry, stomp and throw a baby fit! I want my husband to stay home for more than 6 months instead of always being gone. I want more hellos and less goodbyes. I want to share our children's achievements and milestones with him face-to-face instead of via email and Skype! I want someone else to go! I do not want my husband to go away for a WHOLE YEAR! There will be alot of changes during that year: our oldest graduating high school, our youngest starting kindergarten and many more. I don't want to be the only parent that sees these things. I am tired of people assuming I am divorced because they never see my husband! AAAAARRRGGGGHHHH! Sorry just had to get it all out. This is the crappiest news ever!
