Partner won't stop smoking inside?

I'm pregnant and have been buying stuff for our baby anyway I brought the bassinet and some clothing and I asked him to stop smoking inside. He smokes in our bedroom (that's where I'm currently storing the babies stuff) anyway he pretty much just shrugged his shoulders and said just put a sheet over it. He has turned the curtains orange from smoking, I washed them a few months ago. I don't want our babies stuff impacted by smoke, it's disgusting. I'm about to pack up what I've brought and gonna take it to my mother's house to store it, I shouldn't have to do that. He says I shouldn't be buying stuff so early anyway so it's not his problem (I'm 11 weeks) it's our first child and I am excited and I love buying baby things. Ah I'm so frustrated. Any advice? Please and thank you

Edit: I'm fine with him smoking, dating a smoker isn't a problem but I don't want him smoking inside. I was a smoker until I found out I was pregnant but immediately stopped
