She doesn’t care enough about her boyfriend to consider his feelings, and the well-being of his family relationships, so she should definitely end their relationship. Under no circumstances should she date his cousin! S**t like that can fracture families. Just no.
This. Things persist forever in the era of the Internet. She breaks up with boyfriend and is single for a few months. Send her to a therapist to help her learn about dating boundaries or teach her yourself, but don’t let her go out and make a huge mess of this.
