I know your feelings are hurt but I would also let it go and not say anything. You don't want to get off on the wrong foot. Let her plan her wedding how she wants, and don't put your brother in the middle. It was very nice that your family offered to help. Since she seems to have it covered I would sit back and enjoy the wedding. I liked my mil until I was planning my wedding. I planned it myself and even my parents who were paying for 1/2 (me the other 1/2) didn't say anything. My mil on the other hand who was paying for nothing kept telling my dh she didn't like this or that. My dh should not have told me what his mother was saying but he did. She even said if I didn't do it like she wanted he should postpone the wedding. What a witch. I didn't like her for years after the wedding. I also didn't change anything for her. LOL
