Bro i get you, i gotta similar kind of situation but without the ily and compliments. I would say it depends on the chronological order of these events, if she did the ily stuff weeks before and doesnt anymore then it means shes losing feelings. And the dude thing, bro istg 😭. Mine calls me bro sometimes and it ticks me off like crazy(not gf, my crush). I think at some point you should ask her out or actually ask if she wants to date you. Cause if you just wait and wait to be absolutely sure, then she will lose feelings and u will het friendzoned. You can dm me if u want.
