Croatian citizen traveling thru Schengen with non-Croatian spouse

For the next couple years, my family and I are planning on traveling all through Europe with our camper. I am a Croatian (and US) citizen, as well as my kids. My husband is a US citizen with Croatian residency. Will the 90/180 Schengen rule apply to us? We will travel to each country in the Europe but will never stay longer than 3 months in each one. Thanks.
