Well like the feeling for a married woman with some baggage leaving you holding the bag not wanting her to leave at the time. The "Hurt over a married woman" thing is real. But you know there is that saying about confidentiality agreements. "Confidentiality agreements are to protect the careers of the guilty." At least what I learned in college about them. Because you don't want to be responsible for the divorces so you know you have to! Got to do whats best for your past love!
"Responsibility in a relationship means owning your actions, words, and emotions, fostering trust, while over-responsibility is taking on your partner's feelings or problems, leading to burnout and enabling them, with healthy responsibility focusing on self-care and accountability for your impact, not their reactions." - AI quote.
The point is for anyone out in the mess to note to have responsibility in the frying pan you might be in. Be fair and open and be cool it will be ok!
