Am I wrong? What do I do?

I’m gonna try to make this as short and to the point as possible. So I’ve been with my husband since we were 16 and been married for nearly 2 years now, we are both 21. We have our first baby girl on the way and I’m due in 3 months.

An average day for us is my husband working 12 hour shifts (he’s in the military and sits at a desk all day), coming home, and playing video games pretty much the whole time until he goes to sleep. When he’s off for the day it’s the same thing minus working, he just plays his video games pretty much 24/7. Every single day I am the only one who cooks, cleans, does the laundry, does the dishes, runs errands, grocery shops, takes the dog to the vet when needed, etc. The most my husband does is take the trash out when I ask and walking the dog when it is his turn. I know it is my fault for letting this go on all through these years but now that we have a baby on the way I’m truly over it and I want him to get it together. I’m tired of picking up his dirty clothes in random spots, throwing his trash away when he leaves it out, picking up his dirty tissues from the side of the bed that he doesn’t get rid of, scraping food off of his plate because he can’t be bothered to, picking his shoes up and putting them on the shoe rack where they belong, pestering him to get important things done that I have no control over, and so many more things that make me feel like his mom.

I tried to bring it up to him the other day and he basically gets mad and tells me to stop talking about it. Well, I just brought it up again and he started having a sarcastic response. He thinks working 12 hour shifts and coming home to not help me with anything is okay because he “pays for everything”. He just brushes off what I’m saying and gaslights me until I decide to give up and stop proving my point. I’m just tired of feeling like his mom and literally doing EVERYTHING even on the days he’s off work. Now that our baby is almost here I’m really getting sick of it. Am I wrong for wanting him to do basic and simple tasks to help me out? I feel like small things like him cleaning his plate off or putting his dirty clothes in the hamper/washer isn’t too much to ask for. But honestly I feel like he should be doing more than that, like offering to load the dishwasher or fold a clean load of laundry. How do I get it through his head that he should be helping me out more when all he does is shut me down until I stop talking about it? Or am I wrong and him working 12 hour shifts enough to be able to sit and play video games until he goes to bed?
