Cut my hair?

See, there tends to be a trend with me about my hair and it started it out with the first time that I was really upset and angry and continued on despite friends suggestions (male persuasion) not to. If first was a way to scream at the world and yell at it. At the time the only one most affected and upset besides a few close friends was my bf at the time. He was the cause of it well a big reason. I don't remember what stupid thing he did then but he was good at making me cry without reason (his personal way of saying, I care... jk. He apologized years later).  But I thought the world cared but the reality was that the only one punished was me. I was the one who had to live with it. See I have dark thick hair and some people loved it... so I figured they loved it... chop chop...
I have been wanting to let my hair grown almost down to my waist but I see it isn't going to happen.
And now, I don't cut my hair seeking out to punish those who love my long dark(almost natural black) hair. Instead, there comes a point where something has either caused me a big change that makes me just want to add to the change and sometimes start over. It's not like it's something new, I do it because it helps me cope. And not only that it makes me learn why I don't like to do it after all... Lol... kind of contradictory. I want to and I don't but I do but I'm confused... and this is how I sound in my head. And I know some will say it's up to you... well, it kind of is but it's up to you too. 
Those are my hair last year summer of 2010

This is my hair right now...
and if I do cut it would be about 9 & 1/2 inches...
from the bottom my hair is like 11 inches ... so the bottom would end up being 1 &1/2 inches would would still leave the rest of my hair at a semi short/long layer... right under my chin.
This was my hair like 3 years ago...


 So what do you say...

YES or NO ??   

... to cutting my hair.
