Good day house, I av an issue bothering me over 3year now. I av a childhood friend dating my younger sister and since then I hate him like shit. Not that I want to marry my sister myself, but d problem is that the guy is a player and I don't trust him with my sister. I have also searched myself and i've discovered why my hatred is justified. Reason being that in many occasions have arranged girls for him, and even his late date I was the one that hooked them up. But to my surprise, ever since he has been going out with my sister, he has changed, more religious and he doesn't flirt any more. But my greatest fear is about their genotype, because he is so serious about the relationship, he's AS and my sister is AS too. He knew I would decline if I had known about the relationship at first that's why he hided it from me. But now have found out, and when I confronted her, she told me she's already in love. I told her the only problem I have with the relationship is their genotypes, that she should think twice before she make her decision. She's a serious girl and very religious that's why I love her and I don't want her to make the same mistake our elder sister made, by giving birth to two sickle cell children.
Please your serious opinion is needed.
