Absolutely this, and what @throwawayimplantchat shared.
Sex is a great example of it.
In a healthy relationship, people can feel comfortable clearly communicating their desires - their likes and dislikes. For instance, Partner A says, "I don't like it when you put your hand around my throat," and Partner B says, "Oh I had no idea. I do enjoy that, but I don't want to do anything you don't like. I'll stop doing it." Maybe if it's really important to B, they might have to talk it over, but ultimately, B doesn't want A to feel bad during sex, so won't do anything that makes A feel uncomfortable.
You're scared to tell your husband things like that. And if you do, he doesn't stop doing them anyway, he just keeps going (maybe after stopping for a day or two). If you were in a healthy relationship, you'd tell him never to touch your throat again, and he'd stop and never do it again, and not punish you with anger for demanding it.
But you're not in a healthy relationship. When you're not having sex with him every single night then he harangues you, assaults you, lies to you about what he's done to you, forcibly holds you down, and enjoys it when you're crying or distressed. He's controlling you, and your sex life, through the use of coercive tactics.
