Well this was Oct 2015 and I will say I believe she was... .
I think when we are really wronged and silenced, it builds a certain kind of resentment that can last for a long time. It's one reason I don't often recommend "strict non-contact" (not a term I use, but I see it often). It makes the other person want to retaliate.
When it is done to us, we want to even the score.
People committed to strict no-contact see it as "power". This is an illusion. It is a "crutch". What is the one thing we do with a real crutch. We work hard to obsolete it. Why, because, in a sense, a crutch is "weakness".
Which is more powerful?

Blocking your ex, thinking about it every day, and then unblocking to take a peak and blocking again?

Mentally not looking anymore. Letting it go.

Being able to see an incoming email and not be emotionally weakened by it.
Mentally letting go is power... .not over them... .over ourselves.
It takes time. Just a reminder that the goal is "detachment", not "no contact", and not "winning".
