I think you did good. SHe went from "relationship" to "seeing someone".
Probably you need to send a crucial text now:
"hey what's all that stuff about seeing someone and not giving your number. Is he some Medieval dick-tator?

Let's just be friends and have a cup of coffee! I'm not asking you te be my wife right?

"
Maybe a text like this is a little too thick on it. But I guess you catch my drift. Just keep gaming and LJBF her. And run some BF destroyers when your having her down on a meet. (check straw man technique).
