Idk what I am doing

Hey y'all, I'm sorry if this question has been beaten into the dirt, but I'm not really sure where else to ask.

I'm an nb femme (32) and I'm basically a courier for veterinary offices. There's 2 girls in particular I talk to that get me weak in the knees, but I'm not sure I'm just reading too much into their comments.

Other than just straight up asking, are there any hints or anything? Maybe I'm just too oblivious to notice.
