What do I do? :(

My husband and I have a 2 month old baby girl. I'm doing the majority of caretaking. It's all fine and dandy when he's working, I love spending quality time with her. But when he gets home, he puts on his gaming headset and plays until bedtime. There was three weeks he was unemployed, and sometimes for 16 hours straight, I would have to do it alone. I have nothing against gaming, we actually play the same games together, but if she starts crying, he'll get irritated because he's talking to his online gaming friends. One time she was crying and he had the audacity to shut our bedroom door and rush back to his chair. I was going to the bathroom. I came out and said "was she just crying?" And he said yeah and went back to playing his game. I looked at him and shook my head, which he didn't see, and went in and sat with her and sung to her. Earlier he came in with his headset and she cried, and he grabbed the microphone to muffle her cries and went back out again. If I go anywhere and leave her with him, he expects her to sleep so he can game. If she cries, he'll either text me a bunch of sentence fragments describing her tantrum, or not text me at all and give me the cold shoulder when I get home. I'm the only one that gets up at night to care for her; he growls and shoves his head under a pillow. Then I grab my daughter, and some diapers and wipes, and we sleep in the living room. She's just the sweetest little thing, and it breaks my heart. It brings me to tears telling her "it's okay sweetie, at least mama cares enough to put you before video games, or to wake up and change and snuggle you". I know she doesn't understand it right now, but it's when she's older that I'm really worried about.

TL; DR- husband prioritizes video games before family. Note: wife also games when she has time, but knows when the fuck to put it down and be a parent

Edit: he's also been talking about taking his 5 year old nephew under his wing, because his older brother is literally doing the same thing. My mother in law says "he's being raised by screens", and I want my daughter to have an actual childhood. :(
