Husband (36M) left me (35F) for a Graduating Student. Should I inform her school?

Problem/Goal: My husband is having an affair with a woman who is currently a graduating college student. He already chose her over me and our marriage and I have all the evidences already.

I need advice as I am considering sending an email to her department to inform them about the situation, but I’m unsure whether this would be appropriate, ethical, or could potentially create legal issues for me.

For context, she is a student, and my concern is not about academic performance but about the impact this affair has had on my marriage and family.

Has anyone been in a similar situation? Is there any valid reason to involve the university, or would it be better to handle this through legal channels or personal boundaries instead? I would appreciate honest advice before I make any decision.
