My friendship with one of my bridesmaids has become less so since she'd originally agreed to be my bridesmaid, largely as a result of her not making any effort with our friendship. However, after discussion, we both agreed to make more of an effort. Less than 2 months until the wedding, she has told me that it doesn't feel 'right' to be a bridesmaid. She still wants to attend the wedding but I feel the friendship is over now. What should I do? Any advice appreciated.
