@-rwritess | When you think about it, it's morally wrong, but you can see how it's related to life. When a person is traumatized by a certain individual there are many factors that contribute in the aftermath. In order to deal with trauma, your brain creates barriers or ways in general to cope. One of those ways is SH that ranges in a multitude of actions from skin picking, pulling your hair to extremities I won't mention due to its triggering nature. Another way is embracing the pain and seeking it or in this case falling for the person that hurt you when they show a lovable or vulnerable version of themselves.
When this person has been so traumatized, their mind becomes fragile. There's an emotional and mental imbalance because for so long they've been programmed to react and feel a way that only their abuser has caused. When the abuser sees that this person starts to ''break'' by giving into their lies because that what they are, pure lies, that's when the toxic romances begin. They've spent all this time hurting that person that they used their fragile state to break them down even further until there is no more resistance from them. They start to be nice, kind, supportive, basically all that you want to get you to accept them and eventually fall for them.
In these books I don't see it as promoting toxic romances or as encouraging it. It's educational in a way because despite the book being fictional, there are things that have and can happen. I, for one, was in a very toxic and abusive relationship and I can tell from experience that this is what it was like for me. Manipulation if done correctly, goes a long way. Manipulation isn't necessarily a bad thing it just depends on how the person chooses to use it. I say that it's not necessarily bad because I learned that you can reprogram your negative mind to be positive through manipulation. You have to sort of trick yourself into thinking positive and it helps.
I hope this helps!
