Living with my partner is like living with a toddler

So I’m really just here to vent, please feel free to keep scrolling! I am 33 weeks pregnant and even though I’m exhausted all the time, I dread coming home from work because I know that my partner has probably made a mess for me to come home to. I feel like all that I do is clean up after him. He literally leaves his socks, dirty underwear, shoes, dishes, homework, just about anything you can name all around the house. He doesn’t even put his dishes in the dishwasher when he’s done with them. I ask him so frequently to please pick up after himself to no avail, so I spend countless hours every week basically trying to clean up after his messes. On top of that, I do all of the deep cleaning, laundry, you name it. He acts like he’s doing me a favor if he puts away his own clean clothes. He literally buys something online just about every single day so he is always flooding our home with more things that we don’t have space for, he’s like living with a hoarder and I’m a minimalist who throws away everything. I just don’t know what to do about this anymore, we’ve been together for 6 years and I don’t remember it always being as bad as it is now. I can’t relax unless my house is clean so I pretty much am constantly stressed out because of him. I wish that i didn’t care as much as i did or that i could just look past the mess. I even look forward to him going out of town or leaving for weekend trips so I can have my own clean space for a while. Ugh. 😢😒
