he's acting like a a**

So me and my boyfriend have a 3 bed 2 bath duplex and I'm currently pregnant and I mentioned we should decorate our guest room for a nursery NO ONE comes over for one thing it's not like we ever use that room so the last room is his smoke room as he calls it man cave mind you were only TWO people he wanted a 3/2  🙄 and he goes no we're just gonna add a crib in our room like what the hell no we're doing a nursery So we're arguing about it I'm like 😳😔 are u serious I'm still in my first trimester so I pray everything goes smoothly but I know I will my doctor said I'm good but every time I get paid I wanna buy little stuff for the nursery then diapers & such he's being a real ass saying no for what like are u serious. It's our first baby and of course you wanna go all out and make sure your prepared & stuff ! I'm getting to the point I'm not gonna ask him or tell him anything anymore. I'm also a CNA I work 12 hour shifts and I picked up all week for overtime for us of course( he can't do this at his job)  to make sure my check is decent so I can start saving up and stuff. I'm super tired from work & ive been cramping bad lately & I come home the house smells like smoke the dishes are dirty the trash can is completely full and disgusting. I start telling him like you can't clean up while I'm at work mind you I worked 4 days straight I get up a 5:00 & get home around 8:30 then go to bed around 9:30 so I can get my rest. He also works but through the weekdays 7-6 but fridays he gets off at 1 so as he says I'm bitching & when I was he yells " can you shut the fuck up "but even on the days I work I come home clean and make us dinner. While he sits on his ass and smokes. I'm still pissed at the fact he's being a ass and super selfish I already talked to him about it and hes being a douche! I'm so over the fact he had the nerve to even tell me to shut up & continue to act like this !
