Coworkers!

I, female 22, work in a high profile job where relationships with coworkers are frowned upon. My friend and coworker, we’ll call her Lacy, is 25 and practically engaged to a guy she’s been with for 7 years. Enter friend and coworker, we’ll call him Kyle, is 20 and being trained by Lacy who is his direct supervisor. Last month, Lacy told me she had become close with Kyle and they ended up getting so close to the point where she would stay at his house and they would have sex and sneak around while her soon to be fiancé is at work. He works at the same company just a different job. This has been happening since September last year.

Lacy said she felt guilty and bad for sleeping with Kyle due due to the age difference and the fact that she’s in a relationship. I told her if she wanted to be with Kyle she needed to end it with her current boyfriend. She said no that she wants to stay with her long term boyfriend and would break it off with Kyle. She has not. She continues to sneak around, kiss him, snuggle him, and even in my presence when we hang out.

I need some advice on what exactly to do. I am very good friends with Lacy and Kyle but feel as though they should not in any way be doing anything they have been doing and I have tried to give my opinion and steer them away from cheating. Does anyone have any advice?!?

Edit: so after reading through comments, there were mentions of anonymously reporting to HR. The only issues is that I am the only person who knows besides them. And hint to anyone and both would know immediately it was me. Her soon to be fiancé is beginning to question and she has brought it up that if he found out he would do some not so nice things to her and Kyle. It’s to the point where she has told her boyfriend that she’s with me when she’s actually with Kyle.
