Most Helpful Girl
Dude, just pursue being her friend...
If you actually cared about her, you'd respect her decision of just wanting to be friends. It would be selfish to think of immediately bailing on her because she told you that she just wants friendship.
No matter what her damn friend says, you gotta respect boundaries of the girl who said, "she wanted me to be her friend". And her friend is playing some fucking games by saying that shit behind her own friends back. She's playing some favorable softy shit talk with you. I wouldn't trust it.

Be patient pal, let her get her feet back on the ground, let her settle, forget nasty memories, and perhaps then you could show her what a true partner should like
