I'm not from your ddc but I just HAD to respond.... I can't believe the crap he is putting you through right now. Kick his butt to the curb and don't think twice about how you're making him feel.... momma, he obviously doesn't care how you're feeling or he'd be a little more sensitive at a time like this. I wish you weren't having to go through this right now.
I know it's going to be hard, but try to focus on your little one. That's who is important. JMO, but I think you should tell him you think you're in the early stages of labor and tell him if he isn't going to be there for your support then he needs to find somewhere to stay until after the baby is born because you don't need him coming and going at a time like this.
He acts like he's jealous of the attention an upcoming arrival is getting and this is his way of detracting attention from that and putting it back on him. If you're having to focus on his coming and going then you can't focus on the pregnancy. Please take care of yourself and do what's right for you and your baby. Please forgive if I have spoken out of turn.... I just get so worked up when I see fathers acting like THEY are the baby.
