Should I stop talking to her?

Okay, so I’ve been talking to this girl for about a week. She’s a few years younger than me. And doesn’t have a car or job. She’s already started talking about wanting to get married and have children, which i want someday too but I’m too focused on myself right now. And we went on our first date today, and we kissed but I feel like it is moving too fast for me and it’s kinda scaring me off. And I also need someone who can have their life together, or at least try before I can make a commitment to someone. She’s really sweet but i just feel like she’s moving way too fast and is a little more young minded than me. What should I do? Should I keep talking to her? Should I stop? What should I say?
