Not saying anything may be the right move mom?

My young daughter is cheating on her boyfriend with her 54-year-old boss
My daughter “Kate” is 22 and just recently graduated from college. She has been dating her boyfriend for five years. I love this young man like he was my own.

The problem is, I just found out Kate has been seeing someone on the side. He is her boss, and he’s 54 years old! I’m sworn to secrecy because her older sister told me about this. To say the least, I am disgusted, but I can’t say anything because it would destroy the trust between the two sisters.
