I told her I like her, she said it's fine it's okay, but now she is acting distant

So there's this girl I had a crush on for over a year ( I am a female btw) so 3 days ago I summed up all the courage and told her that I like her, she said ohhh when did it happen, what do you like about me ohhh it's okay it's fine it happens then I asked her if she is straight or bi or lesbian she said oh no I'm straight I said okay it's fine we're good, but all this time I know that she knows that I like her and I heard that she is bi but after all this she is acting a distant only talks when I talk to her, it's not like how it used to be what should I do please help me????? things have completed changed ever since I told her!!!! our friendship is completely destroyed now the only thing we exchange now is hellos that's it, even the hellos only happens if I say hello to her.... It's messed up I don't know what to do I think I ruined it, it is driving me crazy
