I understand your empathy towards your father, especially from what you described, Your father may well be living with an undiagnosed mental health issue, which would make it even harder, if not impossible to believe he was ever in the wrong.
It must have been an extremely difficult letter to write, but I think you made the right decision. Hopefully he will take in what you have said, and find a way to move forward.
Hope your alright mate!
Thank you for your perspective and kind words @philippekiene
All aspects considered, I am feeling alright. It's been a rather exhausting couple of days. This has drained me quite a bit, but even with the sadness I feel, a burden has been lifted. The only thing I can really say, is that when it comes to a situation like this, where the emotions surrounding it encompasses your entire existence, it becomes hard to describe in words. I am sure time will do the healing, and my future will be brighter as a result of my decision.
Thanks bro.
