FI's brother said he is not coming to the wedding today. It is sad because that is the only person FI wants or cares that is there. I thought it was money related so I told FI to offer for us to pay for his ticket. He has not even responded and I feel terrible. My family is coming from all over the country and they really want to be here and are so excited for us. He knows how important this is to his brother/ my FI. I just don't get it.
