No, you didn't. I watched 20 years of it with my sister and her bastard of an ex. Abusers abuse because they are abusive shits.
Part of what you are feeling is because abusers are also master manipulators. They spend years, decades even, telling you that "if you did/didn't do XYZ then I wouldn't have to lose my temper with you." Of course you internalise that message. Doesn't mean it's right.
The other thing that's confusing for the victim is that you become adept at whatever small measure of control you have - my sister, for instance, once told me that because there was always a period of calm after the storm, she would do something "to get the row out the way before the kids came home from school." Again, it's easy (when you're trapped in the FOG - fear, obligation, guilt) to mistake that sort of action for the idea that you're genuinely in control, that you really are provoking things, that "both sides are as bad as each other." Again, this is not true in reality.
Also - think of all those cases where a woman is murdered by her husband and some scummy tabloid manages to get an interview with the neighbours saying "but he seemed such a nice man." Again, relationships usually look okay from the outside unless the onlooker is emotionally close enough to the victim to read her tells correctly, or the onlooker has experience of DV themselves and can see the red flags.
One of my friends used to agonise over her ex (abusive shit) being happy with the woman he eventually left her for (did her a big favour, IMO). I, on the other hand, being a bit more detached emotionally, just used to look at new woman when I saw her out and about and think "there's something dead behind her eyes now - he's doing exactly the same to her."
They don't change. Ever.
