Pls. Pls i need an advice. My sister is dating a yoruba guy for almost 2years now. Fortunately, the guy's younger sister and i were in the same university. Due to d relationship of my elder sis and her elder brother, we became frnd then intimate and we develop feelings 4 each other. We started dating for abt 3 months now. Just yesterday wen i visited my sister. She went tru my fone and saw our romantic conversations. She questiond me and i explaind everytin to her. I was sad and shockd wen she sed it cant work out cos yoruba tradition doesnt permits broda and sister to marry anoda broda and sister of d same family. Pls how true is dis?. How do i make tinz work out pls? I really love dis gal so much and we intended to get married. Though her own elder bro isnt aware yet. I'm thinking of impregnating her so dat notin wil stop us again. Pls advice
