<human>: Can you give me the gist of the text in a nutshell?

Bear with me on this. Me, 22m. Her, 22f. She's part of my clique/group at university, but we never really got along. She's the only girl in the group and I tease her a lot, so we've definitely butted heads. I was pretty sure she hated (or at least disliked) my outspoken, politically incorrect personality I wear in public to hide my insecurity and academic semi-competence. However, we still hung out as a group every now and then, so we saw each other outside of school. Our clique also has a WhatsApp group, so we sometimes traded jibes there.

So we were having a barbeque down by the river when I accidentally cut my hand with my pocket knife (154CM steel folks, cuts like you wouldn't believe). She immediately *ran* over and started fawning over my finger, even though the cut wasn't that bad. I was like, whatever, she just wants to be nice and make sure I'm okay. But later that day, she asked me how my finger was, but in a private chat, not the public group. And since then she's been texting me from time to time via private chat rather than the clique's group chat. And it's always along the lines of "Hey wanna go see movie XYZ?" ... "The other guys are coming too" - which is totally something she could post in public chat, but doesn't?

So just a few minutes ago she texted me again, asking whether I want to go boating on the river. In a second text, the usual disclaimer of "oh there will be other people too but I don't know them real well so I thought you might wanna come?". Now she's not even bothering to invite people from our clique/set. Which, I dunno, I'm terrible at relationships and social interaction, but it's getting kinda obvious at this point, right? Or am I misreading this completely? She treats me totally normal face-to-face at school. I'm an INTJ nerd, I can't deal with this. Explanation... or something?
<bot>: girl apparently wants to spend time with me, tells me so via texts, but doesn't act differently in real life.
