Well, my mother and I are going though something like that right now actually.
We're constantly walking on metaphorical eggshells to try and avoid setting her boyfriend off, and keep all of our opinions (even the helpful ones) to ourselves. He's one of those that thinks he's right...all the time...no matter how much proof he's presented with that he's wrong.
My mother has even gotten to the point where his negativity and harsh critique of the little craft projects she likes to do have sunk into her brain so deep that she can't see anything she makes as being good.

From past instances of this sort of abuse, she's gotten into the habit of constantly apologizing to pretty much everyone for things that, most of the time, aren't even within her control or her fault at all.
Add that to the fact that I've become so protective of her because of all of these abusive men she's been with that I actually wound up sitting outside her bedroom door with a knife a few times when one of her exes and her got into an argument.
To be fair though, they were very heated arguments and I was rightfully worried that the guys were going to hurt her physically.

There was even one man back when I was really little (maybe 6 at the most) that even threatened to set our new apartment on fire and roast marshmallows over our burning corpses if she didn't take him back again.

I know it goes both ways too...I'm sure there's women out there like that.
Part of me feels almost responsible in a way, I kept thinking that if I were just a little older and stronger, I could protect her and give these sad excuses for men a desperately needed lesson in just how much their behavior hurts.
