How to end it

This guy has been really obsessed with me and basically says how he wants to have a family, have me live with him, get married. It’s been two weeks of ft and two days together. It’s honestly too much and we have some differences and he doesn’t even ask anything about me he just talks about how he wants me for a very long time. I like him but idk I think it’s some red flags. What’s the best way to go about it.
