If you aren't getting respect, empathy, or dignity from your partner, don’t offer that in the relationship. Build a relationship around other aspects like having fun.

For instance, You can choose to adopt a dog but you don’t really care if the dog is capable of expressing respect, empathy, or dignity. You are just looking to have fun.

Don't make it deeper than it is, just have fun with it. At the end of the day, humans are going to be here for a while and then we won't be here for a while. Don't overcomplicate it. Just have fun.
