I've had several issues and drama's dealing with my future sister in law (her telling us that she hates, me, I'm a horrible person, our wedding is a mistake, yadda yadda, you get the picture). I eventually decided to let it go for the good of the family and for us to just be civil around each other - but she announced yesterday that she plans on having her cousin and her wear matching outfits at the wedding because they think it would be "cute". To me, this is her trying to get attention, and personally I would be embarrassed if I was wearing the same thing as someone else at an event. I can't say anything because I feel it would be detrimental to our somewhat healed relationship. What can I do? Let it go? Find a way to tell her? Close my eyes really hard and hope it goes away??
