AIO if I tattle on a therapists director office after he bullied me?

My best friend met her ex boyfriend in school - they are both trying to become therapists and currently do hours at a center. He HATES me because he blames me for breaking them up when really I just helped her enroll in some DV courses that opened her eyes to the fact he is verbally abusive. She left him.

He sent me bullying texts.

A few weeks later, he found out she went on a date with someone I set her up with. He then sent me messages called me a r*pist for "forcing her to be with another man" and telling me that I am a terrible mother and my child deserves better.

I really want to send them to the Director of this center but fear escalating. It just really concerns me that this guy is going to be a therapist. I want to do this today so any advice is helpful.
