I am a Senior and I have a crush on this Junior girl. I met around her 4 months ago when we got put into a team in a class. When we were in that team together, we basically talked everyday (about school/class and non-school related stuff). However, now that the teams have rotated, we are no longer on the same team and I haven't had major talks with her since that time. However, a couple days ago in class, she needed help with labeling diagrams and I gave her my diagram to copy off of. She seemed somewhat appreciative of my help and said "thanks." Other than that, we don't know a lot about each other besides our families' history, what are hobbies are, and how's our life. We have never hung-out/talked outside of class.

I sent a friend request to her on Facebook and she accepted it. However, when I sent a follow/friend requests on Instagram/Snapchat and she didn't accept it (she left it on idle). Also, I sent her a message on Facebook asking about something we did in class, but she left it unread and didn't reply.

Senior Prom is coming up on the second week of April 2018 and I am not sure if I should ask her to prom or not. I do really like her because she's a pretty nice girl and she's cute. I plan to ask her to prom next Monday and I don't think I can further build our relationship. If I send her a message, she probably won't even reply. I am not scared of her saying "no" if I ask her to prom, but I am scared of being embarrassed and the awkwardness of the situation if she does say "no."

Should I ask her to prom even if I cannot build a better relationship with her before asking her to prom? <-- If yes, do you think if I ask her to prom, she would appreciate it and be flattered by it? Thanks!
