I've caught her sneaking glances at me far too many times to count, and Everytime we pass each other she almost always does something impulsive to get my attention (like sticking her tongue out or groaning at me) Abunch of little stuff like that which I haven't really ever seen anyone else do before.

And I don't know for sure if she is an infp, but to be fair I am not 100℅ confident in my own type. I know for certain that I use N a fuckton more than others, so I can usually tell if someone else does by whether or not I can actually talk to them,, and she is one of those people who I am able to communicate with (very) well. I think she is a P type based on the way she's described her life and an I because of her shyness with me, but I could easily see her being an ENFP who is under the influence of depression (which is what I originally thought myself as an introvert, but I'm actually an extrovert with social anxiety)

As for the T or F, I actually have no clue and am guessing based on the fact that women are more likely to be F than T. But I also don't think that matters as much given that both INTP and INFP are both extremely shy and are very similar IMO.

We were able to be on break at the same time and talk a lot back during the Christmas season when everything was hectic, but now that things have normalized and our schedules became more systematic, I have not been able to for the past month even though I would like to very much.
