Sometimes change is one of the best things that we can do, as long as its a change for the better. Being the bigger person in a situation does not show your vunerability or a weakness, it just shows that you know how to step up and try to make things better.
Somethings you can tell yourself you don't need in your life, when in reality you do need them. I am not saying that I am the best or that I'm perfect or that I'm better than you, but one thing I do know is how to admit when I'm wrong and try to make any necessary change to make things better.
We ALL still have some growing up to do, but in time things will get better.
