Why is he so concern already about the future?

I started talking to this guy, but he doesn't seem to okay with anything hypothetical I was talking about as far as the future goes.

Prime examble I told him my friend (girl) and I were talking when we both get cars, and a job that pays better than min wage we were thinking about getting an apartment together.

His response well what would happen if you two move in together, and we want our one place. I honestly didn't even know how to answer. Another thing is I told him my parents want to move out of state when they retire in about 8-10 years, and again he ask about what if we wanted to get married. I told him I don't know what's going to happen than. I'll worry about it when that time comes because I don't know what the future holds.

I did go on a date with him, and I ran into a male friend of mine. He was deemed better caught off guard that I knew someone. Later he ask me who was that, and if I ever done anything with him. I told him no we are only friends.

I like him, but I don't like being question already. We only been talking a week, and it's only been one date. Maybe I'm over reading into everything. What do you all think?
