You still have friends that talk to you though , do you ? The others aren ' t there because they might feel too weak to handle how they perceive you . All in all , how everyone perceives you isn ' t that important . How do you perceive yourself ? <| sep |> On the one hand it ' s reasonably normal for a teenage girl to practice her flirtations on males in the family on the other this is far too far . I ' m concerned that your neice has been groomed in some way by older men . The second she sent you a topless picture is the second you should have spoken to your wife and sister but it ' s never too late . You MUST tell them . Show them the conversations . It ' s going to be rocky so prepare yourself for that . Your niece is almost certainly going to hate you , like teenagers do . It may be that you end up in a shoot the messenger situation with your sister being angry at you too for a while but for your niece ' s well being you can ' t keep this a secret . This is in no way healthy behaviour . No matter how much she declares she is not a child , she is . Explain to your wife first , she may be able to help you in ways to approach your sister . If you go for option 2 it will probably lead to bigger messes down the road . She may stop harassing you but then she ' s just going to look elsewhere for that kind of male attention . She needs help . Help her .
