I think you need to find out why she wanted to end this friendship, what about it wasn’t working for her.
It may be that the situation has been changed and this friendship doesn’t really make sense anymore. Sometimes friendships do fall apart as things change, and thats life. Its not easy when that happens, but sometimes thats life, and fighting against it may not make it better.
you dont want her to pretend to become friends with you again and really resent you forcing her into it
