Uncertainty in relationship?

My boyfriend and I used to always joke about what would happen if I were to have kids or he has kids, and sometimes he would say I wish we can have a baby girl together. Few days ago, we had an argument where I said something stupid and he also so we both apologized next day and we got back to normal. Yesterday I was talking about if he has kids, then his planes toys will be ruined by kids. He said this is not the topic now, it’s very far. Does this mean he doesn’t see a future with me?
