Struggles with communicating, help!

I find myself having a hard time communicating with my partner. I am 4 months pregnant and everytime I try to discuss something he views it as an argument when I’m not getting argumentative or upset. To me I’m just talking regular and about something that worries me.

For example, I tried telling him I feel he goes out a lot at night during the week and it worries me because when the baby comes I’ll need help and he can’t just be up and leaving. The only reason why he left tonight was because I happened to be doing my homework for my online class. (I’m a nurse and I’ve graduated already this is just for my bachelors). Anyway, he’s like I’m leaving because you don’t want to lay down in the room right now. I’m just like why can’t you wait until I’m done?

And I guess I’ve been busy all day, I went out with my friend and then later my mom this evening but he was at work during the day. However he’s impatient for me to finish my homework and so he just leaves to go over his friends house.

I call him to question why he couldn’t have waited and yeah idk I just dislike how he goes out a lot at night. He tries to get me to do the same sometimes but I have another daughter from a different relationship so I want to stay home with her to provide some stability and not always be out especially on school nights.

Then he says I’m never happy, when I was just wondering why he went out a lot at night and why he had to leave the house just because I was taking my time and doing my homework. He often goes out and does stuff I don’t make a big fuss and say I’m going over my friends house or be like oh you don’t care about me I just let him go out. He makes it as if I don’t care about him when I take my time and not instantly go to the room like he wants me to. Sometimes I like my own space to get my stuff done and it’s nice not to be under one another all the time.

I also spent my first trimester in bed sick with morning sickness and I’ve finally got my energy back. Back then he complained that I was lazy since I was basically depressed and nauseous all the time laying in bed feeling sick asf. Now I have energy and he’s upset I’m not paying him any attention because I’m doing other things that doesn’t involve him. Sounds like he’s never happy 🤔
