Not sure if I should comfort her or be worried

Awkwaaaard

uyyy... um... that is a very uncomfortable situation.

Yeah, uh...they were boning, and he had to break it off before marriage cuz morals.

Be worried. Start snooping and start thinking about getting a lawyer.

Break up with her man. You don't want a person like that as your wife. For your dignity and self respect leave her. There are 20 million other girls that will love you and cry for you out there. Why would you stay with the one that's crying for another man.
