Glad the SIL situation worked out @Veritek! As a younger sister with an older brother, I can’t imagine caring enough to vent to anyone besides a close friend or two about when the heck my brother chose to get married (beyond the logistics of same guests, etc. that Wendy and others pointed out) and would be on cloud nine planning my own wedding, but! SIL relationships are interesting. And starting relations off on the wrong foot with inlaws is, i know, not what you want to do, so communicating and letting them know your options is great, and i hope you get to keep your date.
