Neglectful husband?

I'm in my second trimester, and my husband seems to neglect my needs. And I mean important things, like yesterday I almost passed out in Walmart and he didn't even walk me to go sit down, he made me take the cart as support and go by myself when I could hardly see and couldn't hear. I ended up throwing up as well and he didn't act like he was worried about me at all.

Now today I've been feel dizzy and faint again, and had to wait for him to come home so I could get food. He then went on to just sit in bed while I cried and told him I needed to go and get something to eat.

I had to almost leave without him before he finally got dressed and acted pissed. Then he almost ran into something while driving through the parking lot because he wasn't paying attention. I started cramping because it scared me so bad and he didn't care. He went into Walmart by himself acting pissed.

What should I do? Please help. I love my husband dearly, and I'm not going to leave him. I just don't know what to do.
