I can forgive in most cases, but have difficulty with anything relating to physical harm, or the threat of it.
Recently been in a situation where a family member threatened physical harm. She's not apologised and is unlikely to. I've not made excuses for her, just remembered her upbringing could be part of the reason she finds her behaviour acceptable. Unfortunately, another unacceptable action by that person either to me or another family member, will inevitably cause me to question that theory.
Life is so complicated....
