Hiya , looking for a bit of advice. Had an argument with my big sister over something trivial,however it got a little out of hand and I informed her yesterday that 15 years ago her husband attempted to get into bed with my wife and loomed over her and kissed her 3 times on the forehead saying he loved her,when we were all on holiday . She pretended she was asleep and he eventually left. I have never told my big sis of this until yesterday as I didn't want to create a fuss. She does not believe this after speaking with her husband -who denied everything . Since that incident happened my wife has been afraid to be in the same room as my brother-in-law. Is there anything I can do to repair my relationship with my sister as she refuses to believe that this incident happened?
