I honestly don’t even know what to do anymore….

So I am pregnant with our third baby and first boy. My fiancé has not seemed to care about anything other than this baby’s name. He wants him to have his name, making the baby the 4th. Every time I try to talk to him about the baby or anything that has to do with him it’s like he doesn’t even care. I’m picking out everything alone. Going to appts alone. Making the registry alone. The other day he even asked when I was due again. I have a hernia in my stomach and I am not supposed to be lifting anything heavy per my doctors orders. I am a stay at home mom and usually take care of 100% of the housework on my own with no complaint. Our laundry room is in our basement so the baskets need to be carried up and down two flights of steps. I simply asked him if he could do this for me because it’s hard for me right now. He won’t even help with simple things like this and then gets mad when I get frustrated. When you pass a name onto your child it’s supposed to be a name that’s honored. I just cannot get behind this. Especially with how he’s acting. It’s making me second guess our entire relationship…

EDIT : I’ve had multiple discussions with him about all of this. It just seems to go in one ear and out the other or it starts a huge fight which is somehow turned around on me.
