So my fiance and his only sister have always been extremely close. On the other hand, I have never been close with her, partially because we have different personalities and live in different states, but also because I find her stressful to be around. The FSIL enjoys conflict and has a history of lashing out at people, including myself. She has obviously been working on this the last couple of years and is getting better, but can still be very stressful and negative. When it came time to pick the wedding party we discussed putting his sister in the wedding either as a groomsmaid or a bridesmaid, but for the same reason neither of us wanted to, instead we asked her to do a reading. While she has not directly talked to me about this apparently the FSIL is very offended and thinks it's weird that she is not a bridesmaid. I chose my two sisters and best friend to stand up there with me. I have no brothers, so this is a non-issue for the fiance. We thought asking her to do a reading was a way to honor her. I also want to emphasize, that even though we've been dating for several years, my relationship with the FSIL is non-existent outside of the few family functions a year. Neither of us text, call, or email the other. I did not realize that some families consider it tradition and expect to include the FSIL in the bridal party. My family is not very big on wedding traditions and my sister did not include hers when she got married. I feel like my FSIL feels entitled and cares more about appearances than actually supporting me. With all that being said does anybody have any suggestions or advice on how to deal with this? Is there anything else we can do to make her feel more involved? Should I call her (for the first time ever) and try to talk it out or just not address it unless she brings it up to me? In the end, even though I chose to not include her in my bridal party I do want her to feel loved and included and I am concerned this will effect our future relationship. Thank you!
