I don't like Jeremy but I wanna buy him a very expensive ring.

I'm getting married soon and my partner and I do not want children at our wedding. My sister has been arguing back and forth about allowing her children to attend. My partner and I compromised and decided to allow kids at the reception but she was still throwing its about how unfair it is. I flat out told her that if she can't respect my wishes than she doesn't have to go at all. I have received nonstop backlash from the rest of my family. I understand that I was harsh, but I tried to compromise with her. It's been a little over a month now and I'm starting to wonder if I could have done something different to keep the peace between us.
