Is she not interested or what?

Okay I think she is intersested in you but maybe not as much as you're into her, I dunno, depends on how she acted on your date. I think you should just call her or text her and tell her were you wanna go, I think the beach sounds good cause it's relaxing. If she say's yes that you've got a chance dude, if she keeps putting it off then it is clear she doesn't feel the same way and then you should move on. Hope this helped.
