Pregnant and my father doesn’t care

My father will cuss not at me but towards me when we don't do that. That’s never been our dynamic within my family. We've always been close but since he has no where to live now I've allowed him to live with me. He has no where else to go.

He knows I'm pregnant and he'll ask me to bring huge cases of waters in. He'll also ask me to pick up heavy things like my dog to put her in the car to take her walking. He's 69, so I get it. But at the same time I don't because I'm pregnant. He will have heated discussions with me, knowing I don't back down, and knowing I'm pregnant and I shouldn't be going through all that stress. And the discussions are over him not wanting to go to the dentist. Dumb I know. I sent him a long paragraph saying to not speak to me at all if he is just going to be disrespectful towards me, he didn't say anything. I don't know what to do, I'm crying every day because of him. And I hate that I'm doing that to my baby. My grandma brought up him being a grandpa and he said oh shoot I might be a great grandpa who knows… like he just doesn’t care. He’s never expressed happiness over meeting his future grandchild or even give me advice or ANYTHING. 😞😞😞😞🫩🫩🫩🫩
