Pre PCS pms'ing

I don't know if other husbands act like this, but I think my hubs might be having a pre-deployment/pcs pms kind of time. He was supposed to leave this coming Saturday to go to Korea for a year. Well the AF messed up his medical clearance and he had no orders, so he applied for a one month extension. He now leaves in a month. Ever since that extension got approved, he has been acting differently. He snaps at the slightest thing, he jumps down my throat, he is being harder on our children, and he is so damn defensive. He asks my opinion, then gets pissed off when I share it! Then if I go the other route and say I have no opinion or nothing to say, he gets pissed then too. Do other husbands act like this right before they leave? Anyone else notice it? Tonight, when he came to kiss me goodnight and say I love you, when I responsed with "I love you too" he came back with "Yeah sure you do!" Now I am pissed over that. I didn't even do anything. All I said before that was that I did not want to have yet another argument over our teenager and what she has done or hasn't done today. And I get "Yeah sure you do!" when I say I love you too. The worst thing is that tomorrow morning he will wake up and act like it never happened. But I can't do that. When my feelings get hurt, I need an apology at least. I did try and ask him if he was stressed about the upcoming move to Korea (for him) and if that was maybe affecting his mood, and all I got in return was "Why are you on me so much lately? Why I am to blame for everything?" So I gave up asking. I don't know...if this is how the whole month is going to go, then it can't go by fast enough! If your hubs acts like this too before leaving, please share. At least that way I know I am not alone.
