I have a fairly small family, with only 2 female cousins, and they are both sisters. I really want one in my wedding as we are very close, but not the other. She expects to be in my wedding, and has already informed me of the type of dress she needs to wear and I haven't even asked her to be in it. She is very negative, and has done a lot of bad talking about me. Type of person that puts people or things down to make herself look or feel better. Every time I invite her anywhere, she causes some sort of drama. We rarely talk anymore because of this. I feel like if I don't have her she will blow up and I might upset her parents. We haven't chose our wedding party officially because of this. Groom has 4 people on his side, and I have my Moh, grooms sister, my sister in law, and want my one cousin. Just want some opinions. Feel like maybe I should have both or neither. Any advice would help...
