My in-laws don’t show interest to meet my side of family

Hi, My husband is a wonderful man. My in-laws live an hour from me and my husband. My Mom has passed away, but I have my sister, her boys, and my Stepdad in my life. My in-laws have only met my sister once (at our wedding) and has never met my nephews or Stepdad. My in-laws have shown zero interest in meeting them, which really hurts. I would think they’d want to get to know the people who I love. My husband is very close to my sister and our nephews and my Stepdad, by the way. Should I facilitate a meeting between my in-laws and my side of the family , or just let them stay apart? Thanks in advance!
