About my best friend.

So we are friends from 11th class . She was very close to me , I am type of girl who don't like to show emotions but still she understands me . But after 12th class I took drop year and she joined a college. When she start going to cllg . She made new friends and she used to put their stories on her insta . And I used to feel jealous (like you used to say that I am ur best frnd and now u are doing the same thing with them.) I was preparing for jee and it start affecting my studies so I told her once about all this . So she said she needs them bcoz she have to spend 3 hrs in cllg . So I said then don't do this thing . But she said they told me to put her stories . Then things got worse and we spend talking to each other . But few days ago she told me she is sitting alone from last 2 yrs and she feels alone . Now she wants me back and I also want to be frnd with her . But I am not seeing that efforts from her side and it's kinda making me angry . So what should I do now ?
