I guess I can see both sides of this. I can understand that you would like it to be just family, however, before my husband and I got married I was the "new friend" and purposefully "not" invited to a family function. It quite honestly did not make me feel very welcome and now we are married and I am "NOT" close to my in-laws at all. This new friend may end up being your sister-in-law someday. I guess I am also just not sure why you would oblect so strongly to her being there? If it is a cost thing then ask your brother if he could pay for her meal...but if it is something else, maybe it is your brother that you have issues with and not her? Or is it issues with Mom? I am just not sure why it would be such a big deal? My mother-in-law before we were married would not have me in family pictures even though we were living together - sometimes a gesture as small as not inviting her can cause years of issues. I would reconsider...Just food for thought.
