losing hope on a girl! please help!!!!?

i like my friend and we have been talking in school recently and i thought things were going well...

then all of a sudden it seems like shes been ignoring me, and its not in a good way. shes not like blushing and looking away. shes just straight up doesnt seem to notice me, and weve been friends for a few years.

i txted her this a few nights ago...

"hey, how did ur mom like the cat?" (she bought her mom a cat for christmas)

she replies "obv"

it doesnt make sense and she made no effort to have any conversation or at least give an excuse not to talk to me

idk whats going on, nothing changed and now she is just wierd

should i just move on???
