<human>: Summarize the given text in a few sentences.

little background first, sorry, it helps. I(18 guy) am the kind of guy that likes to make stuff special/unique. My Junior year promposal was driving the girl an 1.5 hours away to this store where she made this teddy bear and I had the workers in on it so that I could slip the voice thing into it that I recordered beforehand. Then my first gf I asked her out a week before halloween and so I carved GF? into a pumpkin and filled it with her favorite candy and offered to give her a ride home that day, and when she got to my truck I was sitting on the hood with the pumpkin. now my senior prom date is really into harry potter so I made a golden snitch and had a cute little seeker saying with it.
Now the actual part I was looking for advice on. So my prom date, lets call her Sarah(17 female,my current crush), is the girl I am looking to ask, I have been getting feelings for her recently. Looking back I am thinking she is into me, she hated my past relationship(pumpkin GF? relationship) because of how that girl treated me and she was wicked happy when it got broken off. There have been various signs of her liking me, a bunch that I noticed after reading some reddits about guys not getting the hint. Also we have a set of mutual friends and they are trying to push us together for stuff all the time. So I was thinking of asking to be my gf during prom as we are going together. I was gonna wait until the last slow dance and then say something like "I know in a couple of months we will be going our seperate ways to colleges far apart and we probally wont see each other much anymore but I want to spend this summer with you if you'll spend it with me."
I need advice on how well this might work and if I should change it/add to it.
<bot>: gonna ask a firl to be my gf for the sumer at prom before we leave for college, need advice on my method of doing so.
