<human>: I'd bought some stuff which I knew she'd like for her birthday. I want to show her that I like her, but I was not certain if it'd be okay to gift her something not entirely cheap lest she felt it's a bit too much! In any event my friend group is getting together to throw a party for her in a week as well. Should I just gift the stuff on behalf of the group? She'll know I bought it and that I was thoughtful. But would that in anyway mean that I am signalling that I like her only as a friend?

Can you condense the text into a few key points?
<bot>: Overthinking about whether I should give a crush/friend a slightly expensive gift (~$50) and if it'd be creepy.  Also overthinking about whether I should include the friend group in it.
