I am MOH for my future sister in-law's wedding (fiancé's sister). She has four other bridesmaids and no one else has contributed anything to her wedding. I planned and paid for the entire bachelorette and bridal shower, and am the only one who had to buy their own dress. After the bridal shower, she gave everyone in her family/bridal party a small vase with wildflowers except for me. She texted thanks but has not acknowledged my work in any other way. I'm not sure if this is a lack of understanding of bridal etiquette or if she's ungrateful. I am incredibly hurt since I have spent a significant amount of time, energy, and money without thanks. How do I bring up my concerns without sounding rude?
