I Need Help Deciding Whether too or Whether not to.

My School is creating this event for the Christmas in which I can purchase a Gift and have it be Anonymously delivered to a classmate. Now, my issue Isn't deciding Who to send it to, but rather whether I should send it. For the Longest time I have had a crush on someone, however just recently we had a small confrontation of sorts which was quite awkward to say the least. She informed on how she's already seeing someone (I don't want to sound like a jerk but I both hope she isn't, and I also don't see her with anyone else, not like I am stalking her to know, but I just hadn't seen her with another guy whenever I do see her, so I have suspensions, but they aren't out of the picture) and we've just been awkward ever since. No one asides from the two of us know of this situation, and really we're good at hiding it (except me, my legs feel weak just being in the same room as her) but now I really really want to send her a gift even if it's not on my name BUT the issue is! How would she take this? Could she take this as me trying to be romantic with her again? (I don't even know if I want to try and be romantic with her again considering how she already showed how she isn't interested, but rather I could send it over to show I don't hate her or have anything against her considering how I somewhat avoid her, but I also think it's too much to send her a gift) I really don't know what to do.. Even worst would be if she IS with someone and what HIS reaction could be! Hopefully he's mature enough as to not be insecure over anything between him and her, however I can't take the chances and even then it's incredibly rude from me to send over a gift. (The gift is at most like 25$ of Christmas treats) I Reallyyy want to send her a gift, but I know the repercussions and dangers in doing so. Please Help!
