Venting - DH making me crazy

I wrote a huge venting post but it was eaten by cyberspace.
DH is driving me crazy. I know I need to back off my expectations and take him as he is, remembering that I am not perfect and that I am terrible at expressing my true desires.  He is just as bad at it.  He is probably more stressed out and depressed than I am, so it's no wonder he gets all bent and mopey at the drop of a hat.
I'm just glad he's going back to work tomorrow.  That is terrible of me to admit, seeing as it hasn't even been 48 hours of him being home, but he has ideas of how things should be and I have ideas how they should be and I feel like I am constantly biting my tongue and trying to keep the peace between him and my teenager.
I wish I could have a vacation.  But I know that if I ever leave, I have to come home to chaos and overwhelming expectations.  I don't know if this will ever change.
I know I have to take responsibility for how I feel.  I am not mad at DH, I'm just tired of trying to be everything to everyone, when I know I can't do it.
