just need an in sight

My husband lost his job back in august ever since then he's been unemployed, well our relationship has gone down hill from there, he treats me horrible, ignores me, doesn't spend time with me, always wants to be by himself, gets upset if I go near his computer and says "I'll break it", keeps calling me "stupid" and if he does speak back to me it's in a mellow dramatic asshole voice and a simple "fine" and I get nasty looks. I am pregnant with our second child and am due in may... but I no longer want to be treated this way... We also already have a daughter, and every time I try to take care of her he pushes me away and does it himself like I can't do anything right..
