text: my brother has a secret...? my brother cheated on his girl, they have three kids together but arent married and he cheated while she was pregnant with their last child. i told him not to, but he did it anyway. the child contracted clamidia from the cheating. his girl has asked him questions about it, she knows he cheated but he just denied everything. he's thrown me under the bus with my girlfriends and even had sex with the mother of one of my children.   the only reason i havent told her is because i like her and i think he is better off with her. she asked and i told her that the truth is there but it's not for me to tell.   should i hang him or leave him alone? how is it better for her to stay with a guy who cheated and gave their child a disease? tell her!
