Nursery dilemma

Ashlea
So my fiancé and I bought his grandfather's house in February and we have done SO much in terms of improvements. The walls in every room had panneling that we took down and we retextured and painted the walls and painted all the ceilings and we removed the gross old shag carpet throughout the house but the only room that we didn't remove the carpet from, and that is going to be the nursery, is the middle bedroom because there is tile underneath where everything else is hardwood. That room also has knotty pine on the walls with a dark varnish that I am in the process of removing so I can whitewash them to make the room brighter. Anyway I'm starting to get into a panic because I'm 26 weeks and getting no help at all trying to get this room done and then my fiancé keeps saying that what we (I 😑) get done in that room is how it will have to be and that includes removing the carpet to put new flooring down because we don't have the money to get it all done. But we do have the money for it, he just wants to use it on something for himself. And I know we have already put so much time and money into this house but this is really important. That carpet is ABSOLUTLY DISGUSTING. The whole room smells like dust because of it and I refuse to keep it in there. It would be SO unhealthy for our child. Every time we talk about it he gets kind of mad and says that he would like to use the money on something he could enjoy since he hasn't been able to and I don't want to be a bitch about it because I do understand that he needs to have things for himself but this is just so very important and I don't know how to even talk to him to make him understand. Leaving the carpet is not an option. How should I go about making him understand the urgency of not having something in the nursery that could affect the health of our child?
