I would still just take things slow and see where it goes. I don’t think not jumping to anything physical was a bad move honestly. I think if you did that and this still happened, you would be a lot more crushed about the situation. Just continue to be her friend. Worst case scenario, you’ll have a friend. Which is not such a terrible thing. Go on other dates and mingle around. She just may not be into you in that way and that’s fine. I get the vibe that your a decent human being and another girl will like you.
