<human>: Can you succinctly summarize the text in 1-3 sentences?

I matched with a girl on Tinder last Monday (August 29), and we went on a date that Friday night. It was a nice dinner, and afterwards we made out. But the next day she told me she told her friends I'm her boyfriend, and started saying things like I'm stuck with her forever, sending racy pictures, and is buying me gifts already.

At this point it is moving at hyper speed for her, and WAY too fast for me. My ex and I recently decided to take a bit of a break, and I downloaded Tinder just as a way to take my mind off things. But she's acting as if we're already in a relationship. She even bought tickets to a baseball game next Saturday as a gift to me without asking what I was doing that night. A very nice gesture, but it's off putting considering how I was already feeling.

What is the best way to distance myself in this situation? I'm green at dating, having only been in a few handful of relationships where we fell into things. I've never been pursued so hard (or at all) in my life and the situation is making me uncomfortable. I'm not sure how to handle this. I would appreciate any help!
<bot>: This girl is moving so fast I'm uncomfortable, telling people I'm her boyfriend after less than two weeks of talking. What is the best and least hurtful way I can distance myself?
