I am a 24 year old girl. I am in a relation for the last 6 years. We are in deep love with each other. We are not married. But very soon we want to get married. But there is a question regarding our relation. Actually we share a family bonding too. My mother’s father, who has a sister and the sister’s daughter, is the mother of my boyfriend. My question are-1) is our relation right to carry on legally? 2) Is there any problem which can affect our next generation? What’s your opinion doctor? Please help me.
