I am in a serious dilema. I met a guy in june last year. We became frnds then lovers. I loved him so much and he also loves me. He told me about his past how a girl he dated when he was in abuja cheated on him, betrayed him and ruined him financialy. Last weekend, i traveld home and tell my elder sister(same mother but diffent father) about him. I showed her his picture. It was then dat i discoverd that my elder sister was her Ex he told me about. She confirmd all wat my guy told me abt her saying it was her frnds that pushed her to do what she did. Now she said i cant date or marry him because it is bad and a taboo for 2 sisters to have sex with same guy. I disagreed with her and she told our mum about it. Now mum is also saying the same thing dat i cant marry my sister's ex... I called my guy and explained everytin to him. He said he is not ready to loose me for any reason. Now i am confused and in between of love and family. Pls i need ur advice
