"no one knows you
no one knows your OLD mistakes
no one knows your OLD behavioral patters"

for many years i have always done exactly the way you say - i leave, i change job, i "run away" from the problem spot exactly for the reason you point - no one knows my old "me"

and the result is - everything repeats next time, with next friend, partner etc...

my experience shows that this is not the correct way as the problem lives inside me and as long as i'm acting in the way of changing environment - this is just a cosmetic change

isn't it more correct to stay as long as the internal change is really done?
in an emotionally unstable state as is mine right now - it should be wrong to make a decision...

the actual problem is that now i have given her all the freedom she needs but i'm hurt because she doesn't use it for growing up but instead she is careless

as soon as i see that the given freedom really makes things positive - i will be happy
