I (17F) just told my bf (M17) of two months that I can see a future together and he said that it was "Neverland"

I've been seeing my bf for about 2 months and we have talked about moving in together, marriage, etc in the past. He has never complained or said it was too early before.

A few nights ago, I sent him a listing for some apartments near us. For some reason, he randomly changed his mind about us moving in together, saying that the future isn't something we need to worry about and that its "Neverland" until we've been together for at least a year. Am I insane for bringing stuff like this up this early into our relationship?
