I Love Lesbians Who Turn Girls Lesbian

I've had a few crushes on some girls, and I kinda flirted with them. (well, I'm not a very flirty person, so I consider it flirting, but its more like we just hang a lot and talk and chill, then I share my song with them) And with every single one of my crushes, I become like super close friends with them, then I guess when I kinda give up cuz I figure they're straight we grow apart a little. We still remain quite close though, it's just that these girls are never within my social circle, like their friend groups are different, so obv we wouldn't see each other as much unless I had a crush on them and made a point to reach out all the time. But recently two of them have started acting weird. One acts a little hurt, and started posting stuff about a person that's very obviously a crush, and I asked her cuz she seemed a lil hurt, and she said 'no it's not that I like someone', which was obviously a lie. SOoooo, Idk, she doesn't have anything much to hide from me, cuz we've told each other a lot of deep things, so if she's lying there's got to be a good reason. I have a grand total of one close guy friend in school and she doesn't know my external friends. So if the crush is one of my friends, which is unlikely cuz diff social circle, it'd be a girl. But since she's acting weird around me I'm making a few assumptions. I have a crush on another person now so it's not like I'm hoping for this. (thought she was straight cuz I took her to see a concert and still nth progressed)
Another person, is this girl who I had a crush on for a while. We met during a school trip where we spent a really long time in a small group of 20 in the literal wilds of Africa for a good part of a month. She kept texting me, "I love you best" and stuff, and at first I figured it was just bad english or smth, she just meant like love you lots or something, which everyone sends to each other anyway. But recently she said that again, and I decided to call it out, and she actually said 'its a but cringey but I do like you a lot more than anyone else' ( and what a thing to say when she has a group of best friends, and she's pretty close to quite a few people )
Like... idk man, thought she was straight too but she seems a bit more... different whenever she sees me.

Man, what did I do.
