I mean, I understand how ur confused, I am too and I’m not really sure if it’s phase or not, probably so.
I think I’m bi due to how whenever I ask my parents or elders how they found out their crush, it was mostly every same expirence I had for a friend I used to have which was female. I always though of her, I wanted to be around her, I thought of her as glorious things, etc. I asked my parents if they felt these ways when they found each other, and they agreed, saying that’s what they usually felt near someone they had a crush on. I’m pretty much almost 13 and have only had one female S/O at the beginning of the year, though we stopped dating VERY soon as we realized it was way too early to be dating, and we lost touch. I try to avoid crushes knowing I will fall out of interest very soon, and it works. I hope this helped but I have a feeling it won’t. Sorry for wasting ur time if h find this silly or ridiculous. Have a good day :)
