So I followed this girl on twitter and she followed me back. Then two weeks later I direct message her telling her that I think she's cute. She responded "that's very nice for you to say" with a smiley face. Then i proceed to talk about a tv show we both enjoy watching. Then I find out that we both go to the same high school and are in the same grade, I just happened to never have seen her around (fail). And yesterday I told her that she seemed like a cool girl. She responded "why thank you :)". Now reddit, I kinda have a crush on her because she's really cute. I'm not bad looking but otherwise I have been told that I'm good looking. But I still struggle with some low confidence and approach anxiety. Now what would you recommend me to respond or do in my situation? Any tips would be great!!
