A girl into initially seemed really interested, but something changed.

I met this gal at the gym a few weeks back. I gained the courage to go talk to her and to my surprise we exchanged numbers. At first she was texting me a ton, replying super fast and seemed pretty interested. She told me that she didn’t know what she wanted with men and I insisted on that I was different. I had flowers sent to her work for her bday ??. She told me how much she loved them and how sweet I am. My friends told me that I should drop her, but I’m turning to you guys instead.

Edit: I forgot to mention nothing has changed after I sent her the flowers

Edit: My bad I left this part out. After she told me she didn’t know what she wanted with men. The fast replies stopped, most of the time I’ll hear from her every 3-4 hours and the conversations are awfully short.
