Girl question...
So I'm a senior I'm high school and not that popular and very shy but most people are cool with me, I honestly don't think I'm bad looking but who knows anyway I wanted to ask this girl that I have had classes with for 4 years but never talked to go to the upcoming prom with me so I did I was kind of embarrassed to ask I'm person in the 1 class we have so I dmed her on group me asking her "who are you going to prom with?" and she replied with a couple hours later "Me." I don't know what to say next I like never talk to girls and have never gone out with any or had any romantic relationship I'm 17.. I've never talked to the girl but think she's super nice and she's really smart I've figured from the classes I've had with her I just don't know what to say next...help?
