So I matched with this girl off bumble and we chatted for a bit before I asked her for her number, she asked if she could give me her snapchat instead and i told her that I dont do snapchat and so I dropped my number instead and told her to text me. She ended up hitting me up and we chatted for a bit again before I told her to come along on a date with me. She then goes on to say " Umm I amma good. " I then asked her why did she even text me in the first place, to which she said "nvm then"

?????? Can anyone help me understand what I got going wrong here? I've been developing my game pretty well but I feel like I did nothing wrong here.
