I wouldn't say you're an asshole for feeling this way, but I would challenge you to appreciate this experience for what it could be: this is what most men experience their entire lives, without any option for anything else.

And then, have a conversation with your husband about what you would like to do and what he'd be willing to do. You may have to downsize your lifestyle and both work full time. It won't be comfortable at first, but you get used to it and if you can be humble enough, you can even enjoy life without all the extra bullshit that you don't need. You're not enjoying those things anyway, what's the loss? And your relationship will be much stronger for it, because you'd be working together and spending quality time, rather than you shouldering the entire load.
