I went on a couple dates with a girl and it went well. I figured she liked me based on how it was going and we kissed. Somewhat surprisingly, the day following our second date she told me she "really think we'd be better as friends." in a text. We have communicated since then, but the friendship does not seem to be happening. I am not some meek guy that this happens to often, and she does have legitimate reason to not jump into a relationship. But lately I have been thinking that if I don't do something she will be out of my life entirely.
I have an idea for a big romantic gesture that she would like, but I figure the failure rate is pretty high here. My intentions are good too, as I am just trying to keep seeing her and not trying to sleep with her or full-on date her.
Any similar situations or advice?
