This is an old story, but I have always wondered if I was the bad one. I had a friend (let's call her Rachel) from 4 yo to high school. We always told each other everything and his family treated me like one of their family.

She has always been a bit of a liar, absurd lies, like asking if she have done her homework and saying yes but not really. In high school, I went through a very bad time for family reasons and she fell into depression. I tried to support her but I was dealing with my own problems and she ended up giving me a lot of negativity. I walked away from her, but later we worked things out.

On the other hand, time after she told some friends that her mother had beaten her, I don't know if this was true or not, because my friends went to see her and her mother denied it and she was supposed to be fine.

She retook a year and although we were further apart, we were still friends. On his 18th birthday he was going to organize a party but apparently there was a big fight at his house and everything was cancelled. They took away his cell phone and she was saying that it was his own decision because he was better off without it. Then one day talking to her and her mom, I mentioned a mutual friend (let's call him Jay) and there was an awkward silence that I didn't understand.

In time I was able to join all the threads. Another friend (who more or less had reliable sources) told me that Rachel had IMPERSONATE Jay's identity on Instagram. She posted his photos and had a long-distance relationship for a year with a girl from another city. It all seemed too crazy to me.

Rachel had opportunities to tell me what happened for two months and she didn't. So I ended up staying away from her. I was starting university and I wanted to solve pending issues, so I told her that I knew and that is the reason I distanced myself. She did not assume anything, she said: well, you have decided to believe what they have said because the story has been greatly exaggerated. I think that there are details that can be distorted but impersonating an identity doesn't have much to entangle.

AITA for having walked away from her? Sometimes I think about it and I could have asked her for her side of the story, but she had TWO months to do it and she didn't have the courage.
