The other part of the dynamic is how we act around different people. Some people don't bring out the best in us and it occurs at such a low level it is next to impossible to perceive. Happens slowly and over time.
I agree, we change and we stay changed. But we don't truly know until tested, no?
The trick to a relationship with anyone, friend or otherwise, is to change together and to work to bring out the best. Think about your relationship with your best friend. You each have your faults. But you choose to overlook those faults. But when you look at yourself you look to see if your friend brings out the best in you or not. If you like who you are around them.
Would you revert to your old ways? Possibly a real concern there. But what I find more relevant is if those ways were really you or if they were you reacting to somebody else.
If the latter, then if that person isn't different (i.e. hasn't changed) then you may very well react the same way.
I doubt it though. You learned too much and take different paths now when faced with similar choices.
As my IC once told me, you have different tools now. You've upgraded
