<human>: Give me the gist of the text in a nutshell

Hey guys,
I was wondering if any of you guys had any advice for my crush on this girl. We are both seniors in high school and I've been friends with her since the beginning of this year, but I've known her since 9th grade. I'd say that we flirt fairly often (hold hands, laughs at my jokes, etc.) and we get along well, but other times I just feel like she doesn't see me in the same light that I see her. Not sure if this is just my insecurity or this is actually how she feels. We are on holiday break and don't get back to school until early January, and even then I don't see her very frequently (we have different schedules). Should I ask her out? If so, how should I word this proposition (length) and what way (text, FB message, etc)? Thanks in advance for your help.
<bot>: I like this girl, not sure whether or not to ask her out and how I should do it if I am going to do it
