Totally agree, NC has empowered me.
In my case I haven't initiated contact since we split but I responded several times to her and this kept the negative cycle going.
I have blocked her on every front incl. my email but some of her emails have been slipping through. At the moment she is using a gentle approach to engage me, bordering on pleading with me. I have not responded but it does play with my emotions and it gets in the way.
Can anyone give some tips on how to block someone on Mail Version 7.3 for Mac?
I have followed the online instructions but her messages keep slipping through. I assigned her address to be deleted. Is there another way? My email address is my work email and I can't change it. Please help!

NC has given me strength. For me it's says NO MORE to her. I am able to stand my ground, own my power and send a strong message to her that I am no longer available to her. My self respect and esteem has improved tenfold since I've been blanking her. A relationship with her in any form is not good for me.
NC has been the safest way to get space from her and it has allowed me to detach and go through my healing process unobstructed by her demands and volatile moods.
I find that my stregth grows with every day of NC.
