Her boyfriend was really manipulative and worked on every possible factor that could make 'him' 'look bad' in her eyes. So he literally did everything in his power to eliminate all people from her life at our school to keep her away from his own 'deeds' he did behind her back. I was also one of those friends she was restricted to talk to. Finally, we decided to talk only in our colony premises and while he or an of his friends weren't around and pretended to have a 'fight', not many people knew about our 'plan'.
But he was really cunning and he felt we talked and heard from a few others who are his friends and thorough with the story. So he blamed her again and again but she still lied and so did I. There was this girl who my friend never like around her boyfriend but he never listened to her. He used to sneek behind her back and meet and be friendly with her, she knew it but didn't want to fight over this never-ending situation.
So this Monday, apparently her once-good friend also started spilling her secrets to her boyfriend and he in turn is my friend's boyfriend's best friend and obviously told him. That guy was furious for talking and believing people he had restricted her to. So he broke up and abused her so badly she couldn't stop crying. I couldn't see her like this and supported her the next day along with our another common best friend. We were all by her side but my stupidity surfaced when they saw a picture of 'her ex' with that girl he was supposed to stay away from in a very inappropriate pose on social media. She was broken and realized he was cheating on her all this 1 year and some months.
And I misunderstood that picture to be a private picture of my friend's and mistakenly told my boyfriend, who in turn told her ex's best friend and so yesterday or so he got to know and must have raged on her. I thought she had deactivated her social media so I called her and she explained what happened after my boyfriend told that guy. She was sad and feeling guilty that she lied to him and told me when she hadn't told anyone about the 'private picture' I understand my mistake but I don't know how to fix things.
She has said we are done! I don't want to lose another friend as I have always been losing all.
She isn't talking to me and I think she's back with that guy, I can't even confront my boyfriend because then it'd get complicated and transferred further. I was stupid but what now?
She is my bestest friend since past 2 years and a very supportive friend since 4 years. I don't want to see her alone and lose her. She has isolated herself from everyone else. How can I save my relationship with her? Please help.
