My boyfriend and I are in our mid to late 20s. We've been in a relationship for over a year. He is African and I am Black American. He lives here in America. Also, he has an uncle that lives in our area. Two-three months ago, he proposed marriage to me. I told him that I would like to know his family before I can marry him. He knows my family and my family knows him. He tells me to not worry about his family because they are not here. However, I told him that it's important that I have some contact with them. He tells me that they are less educated and his parents do not speak much English. Also, he told me to just chill and I can get to know them afterwards. However, I told him that I couldn't disregard his family. He said to just leave his family alone and that I act like I want to talk to them all of the time. He said I act like I want the world to know. He said we can just go through the courts and have a traditional wedding later- the easy way. I've spoken to many people from his country and tribe and they've all told me that this is not the usual way that they handle marriage. Something is not right . He keeps preventing me from knowing his family and even on social media he has deleted his family from my Facebook. Last night, he got mad at what I was saying and called me the B-word. I told him that I wouldn't accept that and haven't spoken to him since.

So my boyfriend proposed to me about four months ago and he gave me his mother's ring that she had revamped after she got a divorce, she put a sapphire in the middle and two Diamonds on the side. My question is, I really never imagined having a sapphire in my wedding ring so is it wrong to change the diamond ?
