Watching shit unfold like I’m involuntarily a reality TV show camera man

I’m in a four person friend group.
Person A is dating person B.
However person A still likes person C who they’ve had a crush on since 5th grade.
Person C is dating someone outside of the friend group, but C told me they like person B and don’t know what to do about it.
Person B falls in and out of love very easily and says even though they like A they kinda have a crush on C, and aren’t over their ex.
Meanwhile I’m person D who is sick of everyone complaining to me about they’re relationship problems and the whole stupid love triangle drama.
I could spill all the tea I have, but I don’t know if that would help or just create more problems.
