Sometimes it's better to be alone with your child, than in a situation that is unhealthy for them. If mommy is stressed and unhappy, baby will feel that. You don't want your baby growing up feeling and seeing your SO act like that, plus if he is so unhappy watching the baby for such a short period of time, I wouldn't trust him to do it period. All too often you hear about the parent that snapped, you don't want to risk that.
My oldest daughter's father was like that, he never wanted to step up and do anything, even while I worked, he didn't want to be bothered to watch her, so she'd go to my parents. Then one day when I convinced him to watch her because I worked a short shift, I came home to her, screaming, unfed, unchanged, on the couch, with a bloody gash down her back, and him in the back, drinking and playing his Xbox, claiming he didn't know what happened to her, while she, was 20 months at the time, and saying, "Daddy mad, Daddy scratch me." I left that day and have not looked back. He does not see her. It took months for her to stop talking about "Daddy being mad", she would bring it up out of nowhere, and it would break my heart, because I've never found out what really happened. Thankfully, I was strong enough to move on, and my best friend turned out to be the real love of my life and a better father to my daughter than her own father ever was.
Just don't be afraid to leave, don't wait for it to get worse.
