Abuse has a goal behind it, and a lot of the time, it's about changing the victims behavior. If someone screams at you for not doing X activity, eventually you learn to do X activity. If someone hits you when you defy them, eventually you learn not to defy them. If someone abuses you frequently enough, and you begin to break down to their will... It is possible to reach a point where it may seem like you're not being abused anymore.
They don't yell anymore because you stay quiet and do what you're told. They don't threaten you anymore because you don't voice even the slightest disagreement or need. What used to be screaming fighting arguments have become lectures at your expense. They may even praise you for doing what they want you to. And all those mundane moments - breakfast, the rare kind act - stand out more. Your perception of the relationship skews even more. It's all normal now.
And it's still abuse. It's just reached its end goal - wearing you down so badly that they don't need to overtly abuse you anymore to get what they want. All they need to do is make a joke, or complain to guilt you, or tell you want to do/not to do, etc. etc. The fact that's all it takes now doesn't make what's happening to you less severe - if anything, it means you're in much, much more danger than you could realize.
It's abuse. It's horrific. It's just not obvious anymore... and that's terrifying. You deserve so, so much better. You deserve to truly be safe - not to have your wellbeing held behind fearful compliance. That's not safety. That's not love. That's abuse. It being psychological doesn't make it less dangerous.
