Gender reveal/family issues!

So last week my father inlaw said some pretty shitty things about my marriage and pregnancy to my husband, which caused a big issue as it was all caused by my mother in law. I want to do a gender reveal, and I'm ofcourse including my sister in law cause I love her to death, and my mom has the option to come if she wants(her boyfriend doesnt let her come out to my house often), but I'm stuck on my in laws, I'd like for my mother in law to be there even though she has caused alot of crap over the years, but I really do not want my father in law there! My husband doesnt want either there at all, so I dont know what the heck to do! Ant advice is welcome!
