I have a 4 year old son that lives back and forth between two houses. The first is my parent's house where I currently live and he and I share a room together. The second belongs to his father and his fiance with where he shares a room with a slightly older mentally disabled child and there are also two other children there as well. He spends more time there. My son takes naps there and does not take naps here but has what we call 'quiet time' instead where we do quiet activities. I do not force him to nap because he doesn't seem to need or want it; partly I believe it's because he wants to spend more time with me and his grandparents because he sees us a little less.

Recently the fiance told me that he absolutely must take his naps and that it's a problem that he and I share a room. While I agree that eventually I will move out and achieve this goal, the only other room we have is a small one being used as a library and as my mother's computer room. I do not know where we could put what's in there and it's also my mother's house. When I tried to explain this the fiance said that if my mother truly loved my son, she would give up the room.

Perhaps I do need to be a bit more strict on nap times. But still, advice is fine, but I do not like being told I need to do something by someone else who does not live with me. I also dislike confrontation so when these situations happen I typically cave. However this feels a bit much as it would inconvenience the rest of my household. Saying this however would not stop any opposition so if I say no I will get backlash from it. Should I take what comes at me? I don't know how I could defend my decision.
