"Would you mind if we took some time off?"

How does one handle a situation where a girl says something along these lines? A girl I've been seeing for about a month said this to me last night and I went with the agree and amplify strategy. We decided we wouldn't talk again until Sunday, at which point we would reassess things.

Did I do the right thing here by telling her that "I agree things are moving too fast. We've kind of been hanging out a little too much"

Is there a better way for me to handle this situation? Should I drop things altogether?

Edit: Thanks to everyone who offered their insight. It is genuinely appreciated.
