going on a prego rant. sorry

Ok for starters, I understand my husband has back problems and is basically always in some type of pain. But what I wish he could understand is that I'm not used to what my body is doing, so I feel like I can't even move. Which I can't at times. I wish that when I'm in tears saying, "my back hurts". That he didn't reply with, "my back always hurts" and walks away. I've always rubbed his back for him, but I haven't received the same courtesy from him during this pregnancy. Am I being petty, or do I have a somewhat legit reason to be upset??? 
Ugh thanks for hanging on and listen to me complain because I know no one I know wants to hear it.
