Welcome,
Your story is written wonderfully. I feel for you having a father that was inconsistent. We just need stable parents to bring us up. I am not trying to make excuses for him but the WT probably messed him up loads and caused a lot of his problems as an adult.
Don't make the same mistakes he did and stay completely away from the WT now, it's a dangerous cult and can have a mental hold on people that will cause them to be controlled by WT thinking. Think for yourself and keep on learning about the other side to this religion.
Take care
