Confused about what to do about my situation of being in a should move or shouldn't

I know a girl since my 10th , currently in clg so like i had a lil bit crush on her and she normally reject it and said consider as friend and tbh i someday consider her friend someday not. Last year we had a great friendship like normally talk daily. , having gane time , going home together from clg

So basically what happens these days is that Like around 30 days i think. We usually send reels on insta but these last day she didn't react on any even replied late like 1-2 days . So for some time i stopped sending reel but nothing changed and at that point i feel lonely . And as time passes i thought to msg her and and that normal life begins but it stayed only 5-6 days now I feel that she consider me as her last option that when she feels there's nothing to do she just reply back to me Also i started to be angry on this.

I need yours opinion if u ever had been in such situations , what u did , what worked for u and all.
