Couplesbreak up for many reasons: infidelity, incompatibility, and constant arguments are just some of the most common reasons. But it’s not often that people break up because their partner’s family member might pose a threat to their younger siblings.

This guystarted questioning his girlfriend’s morals after she chose to believe hercreepy stepbrotherover his 15-year-old sister. The woman saw nothing wrong with the sleazeball coming into the teen’s room to “chat her up.” But her brother was having none of it and prioritized his sister’s well-being and safety.

Experts advise reporting harassment even if it’s unlikely to go anywhere; at least there’ll be history of the offender’s inappropriate behavior

The OP and the commenters are right to view the stepbrother’s behavior as a huge red flag. As the experts at Stop It Now!note, inappropriate behavior towards minors doesn’t have to involve any touching. Inappropriately peeking in on a youth or entering their room without permission counts as inappropriate behavior as well.

The FBIurgesparents, teachers, and caregivers to report any adult’s inappropriate behavior towards a child or a minor to the authorities. But, since the OP says he’s from Portugal, individuals may not want to report harassment due to the incompetence of the law.

Or, at least, that’s what the author himselfwrotein his update. He believes that the report will probably go nowhere, as the only evidence in the story is word of mouth. Still, he thinks that if the stepbrother ever tries anything like this again, there will be an official record of his past behavior.

Law experts agree; according toMKFM Law, documenting the harassment can be important for future victims. “By documenting multiple incidents over time, patterns can be established, providing a more comprehensive overview of the offender’s behavior,” they claim.

The girlfriend was wrong to invalidate the teen’s experience and words

Experts saythat deflecting erodes trust and makes open communication difficult. A partner who’s deflecting might change the subject, blame a partner for their own feelings or avoid the issue altogether. Other times, a partner might start acting defensive or playing the victim.

Psychotherapist Sharon Martinexplainsthat validating someone’s feelings doesn’t automatically mean you’re agreeing with them. “We can certainly feel differently, but make the effort to try to understand and empathize with our loved one’s feelings,” she writes.
