I mean, it's a a pretty realistic description of how some 'relationships' play out, both from the victims and the abusers POV. I do understand, that this probably isn't, what most people are looking for when reading or watching stuff.
Most of us do it, to escape from reality to somewhere, where everything is either fine/perfect or at least the villains always get what's coming to them in the end, when in reality it hardly ever tends to work out that way.
But the abuse starting gradually, with the abuser playing nice at first just to become worse and worse over time, and the fact that it isn't always (hardly ever) as simple as 'just leaving' to put an end to it, is pretty accurate to real life abuse cases.
but this is really one the worst I've read !!! No plot, no characters development
