My SIL who is a bridesmaid in my wedding recently lost her mother to breast cancer. I have excluded her from messages and trivial things because seriously my wedding is not more important than allowing her time to grieve. With that said I don't want her to feel like I'm excluding her because I don't want to be bothered or I no longer want her in the wedding. I don't deal with death well, and I'm not sure what to say or do. Any help or suggestions would be greatly appreciated.
