(Back story) For 5 years my mans college friends wife (didn’t meet yet) has been cruel to me over a post that was just an opinion and had nothing to do with them. She messaged me being rude then blocked me and purposely isolated me from outings. Years later they were engaged my fiancé was a groomsmen but backed out when he was told I was not invited from proper etiquette that wasn’t okay. She then gave an insincere apology and said shed start on a clean slate. We finally met and as I thought things were truly behind us. I put in effort for change and was generous and was there for her and hard times.Only for her to call me names, tell me if I come to her house she will call the police and I can’t even be in the driveway. (My fiancé lived there for a little) she was crueler and told me I have to invite them to our wedding. A year later we all go to dinner and I said hello to her husband and was waiting to say hello to her she walked passed me and ignored my existence the whole night. I felt very uncomfortable and felt like crying out of frustration. How do I tell them they’re not invited without her getting defensive or feeling attacked? I wish it wasn’t like this. My fiancé is 100% on board about not inviting them.
