Hubby rant, not supportive....

Let me start out by saying he has always been very supportive for everything else, until now. Yes, he comes to doctors appointments, but it stops there. He was complaining the other day about how the house has gotten so messy and asking why I'm not keeping up with stuff while he's at work. Well, I work too. I'm a nurse and work 3 sometimes 4 12 hour shifts a week. If he is off he will load the dishwasher, do one load of laundry, or take the trash out, and my gosh his head grows three sizes. You would think he was made of gold after doing that one task and hearing the way he won't let me forget about it. He will sit on the couch when I get home from my work day where I have been on my feet all day while I cook dinner or get my son in the bath. He will occasionally ask what's wrong, and my answer is usually "I'm EXHAUSTED" but he won't do a damn thing about it. Sometimes he even comes back and says "well I'm tired too, I had a long day at work." Honestly It takes every bit of my self control not to slap him when he pulls this. (He works 8 hour days and has for 8 plus years) He will sit on the couch and watch while I continue to work even when I get home from work. 

He has never once offered a back rub. He has rubbed my feet once, on my birthday. 

I have tried so hard to explain to him that I'm E-X-A-U-S-T-E-D and that's why I've been letting certain things slide around the house. I don't have the energy to clean the toilets or launder our sheets once a week anymore, and dammit his arms work just as much as mine do. If I would have had any idea that THIS was going to be our life together with me pregnant then I would have never started trying. This is pure misery. Just 6 months ago he was my best friend who I could go to anything for. I would tell him anything and everything, and it had been that way for almost 6 years. Now we can't even sustain a conversation. 

Why can't I make him understand that I'm not just a lazy couch potato? That I do actually come home from work ready to fall over and with my whole body aching? My feet have recently begun to resemble sausages at the end of the day too. 

I have tried on several occasions to start out conversations about it and he shuts it down. It's like he doesn't want to hear it at all. I know my hormones are making me crazy, and I know I am probably unbearable for him at times. But I need him now more than ever, and we have drifted farther apart than we ever have been over the last month or so. I hate it. We haven't had more than a five minute conversation in over a week, and we live in the same house. I HATE THIS. I don't know what to do. I don't have anyone to go to about something like this. I am miserable.
