I am originally Indian. I am divorced. My sister is marrying her fiancée in India next year. I am dating a man for 3 years now and I invited his mother to the wedding. My sister invited her friend to my wedding and I didn’t care. She now isn’t talking to me and said that my bf’s mom can’t come because they don’t know her. My parents are paying for this wedding and my sister isn’t paying a penny, nor is her fiancée. I cannot uninvite my bf’s mother as that’s rude and I’m really not keen to shake our relationship like this. What do I do? I was thinking of scaring her away with stories of dengue fever instead and I know that sounds ridiculous. She’s old and may not want to take the risk. I can’t tell her the truth and actually I’m shocked my sister would be so cruel and weird. Her fiancée messaged me saying the mom can’t come.
