Is she interested in me, and should I confess now or wait?

(Throwaway account because all my friends including her know it)

So, theres a girl in my school that i like. We have been friends for a year now, and i have developed feelings for her. I want to confess but I am scared she’ll reject me.

I think she might be interested in me, but I can’t really discern whether that is just friendly affection or romantic interest. I sometimes find her making eye contact with me. She often comes and starts conversations random conversations with me, but it seems like she does that with our other friends as well. She’s really open to me, and tells me a lot about herself, and asks me a lot about myself all the time, but I asked one of her long time childhood friends about it and she told me that she just has a really open personality.

Also, I want to know when i should confess to her about my feelings, because i think i might have more of a chance if i confess later. I feel like were getting closer recently, as we have been playing games and going out(not in a dating sense) more often. I feel like i might confess too early before she’s ready and she’ll reject me, but on the other hand, I have to leave for another country by the end of 2023, so i want to spend as much time as possible with her.

Is she into me or are we just friends and should i confess now or wait?
