I think we're all capable of darker sides and falling off the track. I also think we're all capable of true change. I'm sure you can think of at least one time in your life that you really reached deep down and changed. Wasn't it sincere?
My very simple philosohy is that life tests us. Sometimes we do well, sometimes we suck and then are booted into changing or letting things go and moving on. We're faced with losing things that matter to us as a result of our actions. Are those things worth changing for? In your Hs case, it was. Is it real, sustainable change? Is it what you need, after the separation, etc? Only you will know.
