Husband day trades but it has at it

I am posting this out of frustration and sadness, I feel like my husband is taking the joy out of the fact that we are having a baby. Background info, he runs a successful tile company but day trades in the morning in hopes of making more money. Sometimes he’s on the simulator other times he trades with live money but he’s been so depressed about not trading well, he’s been at this for two years now so he takes it out on me even though he tells me it’s not me personally. He hasn’t been excited for the baby, all he thinks about is how he “sucks” at day trading and tells me to learn it to that I can help him. I have no interest in it, and when I try to learn hw gets upset that I don’t get it right away. I’m over it. He stays mad all day until about the ending and I’m just done with his bad moods.
