You were a very good friend. She, on the other hand, was not. You did absolutely the right thing.

You were a good friend and did the right thing. Your friend on the other hand sounds like a drama queen

I wouldn't worry about it.

She probably didn't want to involve her family. Lovers quarrel, you know. Maybe that's why she confided in you.

As a friend you tried. But I think she wanted just you to be there for her. You came up with a good plan, just, you sort of needed her permission on it though.

You tried your best. Lesson learned. Next time get the full 411. She should have been more appreciative though. Sounds like youre a good friend. And the boyfriend sounds like a jerk. She can do without him.
