My Fiance and I recently spent a week at my families time share and my aunt stayed with us for a few days. It was the first time she had ever met my fiance and in less than 24 hours she had determined that she did not like him and she wasn't exactly shy about it. She pulled me aside to express her dislike and worry about my fiance, she ignored him and barley spoke to him with the exception of her telling him we rushed our engagement, and also said quite a few negative things to my mother. Her attitude and commentary eventually turned into tension between everyone and made for a very poor vacation.
At this point I am very hurt by her actions and comments and I am extremely torn regarding inviting her to our wedding. If she can't be happy for me and will only keep the negative commentary going at the wedding I do not want her there, however I worry that the drama that will come from me not inviting her will be much more stressful and difficult to deal with.
