What should I do? I looked through my friends phone because I thought she was talking behind my back - and she was - she found out and now she hates me. How do I get her to be my friend again, even though I've said sorry hundreds of times?
Aren't you angry at her too for talking behind your back?
You both did things to hurt the relationship. Things won't get better unless you both decide to own your part and apologize.
Yes, you should keep apologizing for breaking her trust. AND you have to make it known that you feel hurt by her being dishonest with you.
AND you need to make it known that you want to repair things and continue the relationship.
AND you need to be ok with her not wanting to meet you in this task.
Why we she taking about you? What was she getting out of it? You need to truly understand this, and she needs to be clear for herself about it too, otherwise she'll just keep doing it to you and her other friends.
If you tell her everything and then let it go, she'll come back eventually and tell you her story. Then you can listen, and that will help.
