Dating Your Best Friend’s Sister
English football captain John Terry discovered he’d broken an unwritten rule when he dated a team mate’s ex girlfriend. But what about the rules around dating your best friend’s sister?
Is it a total mateship ‘No No’ – indicated in this amusing Hahns Super Dry Beer ad where a man refuses to date his good friend’s sister for fear of violating the Bro code? Would a guy really reject the advances of a pretty girl because she was his friend’s sister?

And are the conventions forbidding dating a best friend’s sister as strong as those around a mate’s ex? It’s a touchy subject.
Rules For Damage Control
Most important is to work out how much damage it might cause to your friendship if it doesn’t work out. How strongly protective does your friend feel towards his sister, and how far will he take the “Don’t mess with her” stance?
Dating expert Renee Piane has laid down some guidelines for dating a best friend’s sister to at least ensure you have damage control in place if things don’t work out:
- Is she old enough to make her own decisions about dating – at least 18 or older?
- Is she cool about her brother knowing you are dating? If she wants to keep it a secret that’s a clue he’ll be upset and you need to be up front with him before you start anything.
- Is she someone that you will see often if it doesn’t work out? Running into her at every party for the rest of your life (if you know she is not a keeper) can be a pain!
- Be honest about your intentions. If you are a player who just wants to hit and run find someone else… it’s not worth the risk of losing a good friend.
