After 19 years, both of my SIL's STILL treat me like sh!t. I'm so glad we only had a MOH and BM. That cancelled out having my FSIL's in my wedding party. I could not have made a better decision. Maybe that's why none of my FIL's didn't show up to my wedding shower. Maybe they are all just a bunch of bitches and it isn't about me lol. After 20 years, you will not care!
