Questions: Flirting

We're both 18 in HS btw.

So I kinda jumped the gun and thought this girl was really into me and already did my v-day shopping for her. It was cute and cheap:

-a card with my thoughts about her in it

-a chocolate rose

- a Pokemon plushie(she's a pokemon fan)

-various flavors of those little Skittles bags that are like .89 cents at your convenience store(It's her FAVORITE candy, so yeah)

All put into a small cute gift bag

However though.. I got the just be friends speech when I asked her on a date for this weekend. Me and this girl have a major history, but to sum it up I've been persitent but laid back and not overbearing with her for the past 5 months and decided to try for one last time.

Now since this "one last time" was shot down I gave her a lengthy speech of why I honestly can't be her friend anymore because it's too hard and bla bla other cute things. I also told her if she'd ever change her mind the offer is still on the table, but I said that in a cool and confident way

Anyway since I knew we wouldn't talk again I sent her a pict of the goodie bag I made and she thought it was "literally the cutest thing anyone was gonna do for my honestly". I spent a lot of time and thought into making this for her. Should I still give it to her on v-day and leave it at that?

Do you stare and try to maintain eye contact? Or do you give quick glances because you find it hard to maintain eye contact? Also state whether you're a shy or confident person.

As for me, it's 50/50. Sometimes I feel like the man, stare them down and give them a friendly smile... and sometimes I feel awkward as hell and end up pulling something like this link
