I still shudder tbh, the evil of that man scared me through the telly!
I now realise that my ex did all that he did through a feeling of weakness, not power. a powerful person, with self confidence and selt esteem has no need to tyrannise another human being, he knows if they want to leave, they can and that life will go on, that they will go on.
An abuser is terrified of not being loved/partnered, cos it means they are truly shit.
Of course they are not, but that's what they are driven by. They have to destroy us, often bright young things, attractive, warm, popular, successful, friendly and caring, in order for them to feel stronger than us and to steal the light they see in us so that they can bask in it.
I now look at my Ex as a pathetic man, weak, insecure, stupid and out and out mean. I genuinely can't imagine what on earth I was thinking even giving him the time of day.
I think the fact that I have changed so much in the last 2 years (am happier and healthier emotionally than I have ever been in my life) means that I am a different person.
This different person wouldn't fall for that crap again, I KNOW i am worth more and I will DEMAND that I am treated properly or I'm OUT...
I have already rid myself of a right controlling nutter, and about to end it with a nice man that isn't into me enough, after a year, because I know I deserve to be loved, not to be with someone cos it suits him... 
I know that whatever situation presents itself, I can handle. I can spot an abuser, I can bin him. If I see behaviour that I don't agree with, I can call it out, If I see that I am not prioritised, or important enough I will end it.
I love myself, I deserve to.
So do you.
Please do the therapy, please don't hold back in doing ANYTHING and everything to heal, and to kind of give yourself the insurance policy to guard against this ever happening to you again.
You really are worth that.
We all are to be honest.
