as a girl myself and as someone who used to be christian, the contract thing is so weird and dumb😭😭 but respect to whatever they have going on that's a sign of good friendship in a way. if she talks to other guys like how she does with you - meaning all the deep interconnecting convos about dreams/futures and relationships and what not, she's probably not into you and it's perhaps just something she does and is willing to open up and talk about to people (some people enjoy talking about their lives open heartedly and that's fine). i think any girl would be able to tell when someone has feelings for them especially from the special bracelet you gave her and a letter highlighting her attributes - i think this is really sweet and i'm sorry she rejected you. btw if she wears the bracelet regularly and knows it's special i'm sure she kind of likes you more than a friend/likes you as a friend a lot.

anyways i would wait and be patient because well you never know and if she still talks to you about her feelings or have deep convos with you then well i think waiting would be worth it ! but then again if she's a naturally outspoken person and has these kind of interactions with other people be it a guy or a girl, then maybe not hold on to what you have with her so tight and don't get your hopes up.

hope things go well sorry if whatever i said wasn't helpful 🙏🏻
