Should I feel guilty によって association cause I knew an LE stalker as she stalked LE and stuff went down?

I could tell a story that no one would believe here, and most of あなた have probably read her fics as she was WAY 人気 (she has LE now I don't know why) but like, my Ex at the time was good フレンズ with her and relayed the events to me as they went down and I was like ASHAMED of the fact that I just listened and did nothing. Now I am so afraid to even try to send LE a letter または something cause I know how weary she must be of her fans, so should I feel guilty about this または just 移動する on and if I ever do meet her handle things like the rational sane person I am? LoL!
