So, you’re a (1) university student (2) in a fraternity who encountered a fellow student (a) who is verbally and emotionally abusing an intimate partner.

(1+2)*A = you are a member of two distinct organizations which have some form of code of conduct, and have at.the very least an ethical responsibility to inform about the presumable violation of said codes of conduct.

Do not begin an intimate relationship with either “Beth” or “Ben”. Especially not out of anger.

Your fraternity and university both should have someone you can talk to about reporting unethical actions, who can refer you to people far more knowledgeable about the rules, responsibilities, and laws that apply to you than pseudo-anonymous strangers on the internet ever could.
