Jerk, spoiled rotten man child

Lately my so has been a jerk. This is our second pregnancy and was his idea (in fact I waited six months past when he started bugging me to get pregnant before I tried getting pregnant) yet he acts like he could care less. We got the first ultra sound and now heard the heartbeat for the first time and he acted like he could care less. All he cares about is his game and he acts like anything I ask him to help with (taking the dog he bought and begged for outside when it needs to go potty-not every time obviously) is ridiculous and like I should just be taking care of everything. Even when I ask him to help me with something I can't do like lift a stone slated table by myself, he acts like it's just not his problem. We live with his parents and brother and sadly a lot of the time I don't want to say anything or nagg because we're infront of them and I hate feeling like that nagging bitching wife. But at the same time shouldn't he realize that I need help? That I'm pregnant with severe morning sickness the first few weeks and now horrible heartburn and I'm in general horribly exhausted and stressed. He has been bugging me for a motorcycle the past month and we can't afford it plus it's completely pointless with kids and he wouldn't listen when I said we couldn't afford it, he basically thought if he broke me down enough I'd give in. So eventually I broke down and cried for hours and we haven't talked about it since. I hate feeling like the bad guy for not giving him his way but at the same time I can't be a push over. I give him his way with a lot of things like a 80 gallon six ft long fish tank that he redid three times with completely different sets of fish which is very expensive,but he got bored of those and got two cats(so they wouldn't be lonely because duh...) unfortunately the litter training he didn't do with those drove me insane and he got rid of them. Then he got a snake which was followed by a dog which killed the snake and now turtles. The dog I mainly take care of (or he gets ignored). I feed the dog, bathe it every two weeks, brush it every week and take it out every day I'm home. I do not do well with animals so this is very stressful for me and it's a lot of money buying all the supplies for all these varies animals only to get rid of them a month or so later. He doesn't realize how stressed I get. Even though he knows I have severe anxiety and depression and that because of the way I was raised and what my home life was like I do not do well with dirty things or animals, people who can't do what they need to exactly when they need to. For fuck sake I have a giant white board chore chart with color coded schedules for everyone in the house. I like things neat. I like things in order. I do not like this and it's stressing me out and I can't deal with it. Anyways though the point of this rant was that tonight is New Years and all he's done is snap at me and do all the things listed above combined with ignoring me over a phone video game and giving me a thumbs up when I tried talking to him about how he's making me feel. So I'm alone upstairs my first New Years as a married woman when I should be able to enjoy myself with my husband. Over all I'm pissed off and hurt. And I'm ranting because I have only one friend who I don't like bugging with this type of stuff because I feel a married couples problems should be kept between them. Unfortunately this has led to me  pretty much talking to myself because he stopped listening to me and how I feel months ago. I'm not upset because I'm pregnant in fact I consider myself a highly rational person but his actions, his way of living is not rational it isn't right and his attitude towards me in general isn't nice.
