Start ignoring him, and he will come around.. that's how I got my husbands attention...
Personally (and I'll admit I'm not good at communicating to begin with) I would leave for a while ie a weekend maybe a little longer. I don't take attitude in general and especially not when pregnant. I would tell him he can be an *** to himself all he wants and when he's ready to act like an adult he can let me know to come home. No yelling, no arguing, no negotiations.
It also could be that he is nervous and fearful of the changes that are about to come. Some men have a hard time expressing themselves instead they just act like complete jerks. I agree with singermomtobe that sitting down and tell him how your feeling and maybe you can get down to the root of the problem.
Men don't get it. My ex used to tell me I was "out of control" when I was speaking calmly to him. He never considered that being pregnant was a real condition. Sit down and talk to him in a few days and explain how he's making you feel. Use statements like "I feel" this way when you do this. Try not to get emotional unless you cant help it...you are pregnant. Lol. If that doesn't work, put your foot down and tell him he's not the pregnant one and he has no right to treat you the way he is. I hope things get better for you. I'm all alone this year, and pregnant, and its terribly hard. Good luck!
