Its a big step forward to see that you have behaviour that needs to change.
How many of us have had the moment we realised that to stop being a victim , is too stop acting like one ?.
Its like we get conditioned into the victim/scapegoat role as a child. And it becomes a pattern we follow as an adult , until we say enough is enough and start standing up for ourselves.
Its wrapped up in a lack of self -love.
Once you start to love yourself (even like yourself) , you relise that no one has the right to be abusive to you in any way.
Thats why , (i think) so many of us have attracted bad partners in the past.Its almost like they can smell victim off us .
Somehow we fall back into the pattern and the partner takes the place of the abusive parent( in a diffent way).
When you spot there needs to be a change in yourself , its sets off a chain of events.( A small change , even just saying no to the toxics now and again.)
These events , can be scary at times, but completly essential for lfe improvement.
Eventually we learn how to stand up to ourselves , and also how to gain respect and admiration from others.(not usually the toxics , but "outsiders "). This is a life skill most children aquire in their late-childhood /early teens....I have noticed that most people i know with toxic parents learn this a little later , we dont seem as confident, but better late than never ! .
This when learned will also help ward off the crap men. Either we begin to spot a rotten one or the confidence ( as in "i dont take no shite vibe" ) scares the toxic ones away as they want an easy victim.
This is what happened with myself.
Going NC is the best thing i ever have done. 
That was the easy part ,it gives you a chance to breath and gather your thoughts. The hardest part was working out what i had to change and why i should. For me it started with saying no.
Last time i saw ex-mother , she was following me around my house , doing the usual critasism and goadng me and twisting what i had said . I went to my bedroom to escape ( remember , in my house , im running to my room like a 5 yr old [blush)
I had that moment.
She followed me , opened the door and came in...spouting her poisen as she always did.
I stood there , just looked at her and said in a quiet voice ...."dont start Mum , you will not win this time."
- HER jaw hit the floor , she turned about and left my house ...didnt say goodbye.
Shortly after that i sent her txt saying i didnt ever want to see or hear from her again.
