My soon to be sister in law got married a few years ago and I was her maid of honor and we are very close but I have two sisters whom I am very close to and they are both my maids of honor. My SSIL has been referring to herself as my "matron of honor" and I don’t know how to correct her. I think she assumed that I was hers and she is now mine.
These three are my only BM and I know my sisters would feel crushed if I made all three of them maid/matrons of honor. My sisters and I are very best of friends; I just don't want to hurt anyone's feelings...
