My Sister in law Didn't invite me to her wedding

My Sister in law an I had some words after she an her family constantly dips into my marriage talking about me an even had the nerve to tell my husband to leave me. She is getting married an I'm not invited after getting kicked outta the wedding an I feel like as my husband he shouldn't go because there is has to be some respect for his wife nobody has to like me but respect me. Bible says Cling to your wife should he just leave me at home an carry on going to the wedding?
