My husband and I have an iPhone 8 and iPhone 6 both on iOS 11.3. We’re on the same Apple ID and want to share that but want separate contact lists, etc. Tried to create new Apple ID but just change it for both of us.

You can't do this.
You can't both share and not share using the same Apple ID.
See Family Sharing. Family Sharing - Apple
You can't do that when sharing an Apple ID. All data for the ID is the same for both persons sharing the ID. I suggest you create a new ID for one of you and then set up Family Sharing.
There may be some data loss, but you can minimize it. If syncing photos with iCloud, ensure Optimization is turned off in Settings/Your Name/iCloud/Photos. Then make sure full resolution photos are on the device. When signing out of iCloud, if asked whether you want to retain data, choose yes. Messages conversations will be lost if they are addressed to the ID. See the article below for other places that the old ID should be removed. Also set up Family Sharing to keep access to your apps.

How can I separate two iPhones sharing data but keep the same Apple ID?
