Hi Jobun,
Mikey tells me we have a better understanding of things when we return to the afterlife. When we have our life review with our guides it is for learning according to Mikey. This history will probably be part of it and she will feel the emotions related to this "hate". Mikey tells me if the soul resists to understand it and ego is still present, your father-in-law may then also be present at that point with discussion with these higher guides as well and with the aunt. It is a life lesson and how do we handle things? Mikey tells me we do not get a pass if we don't recognize our hurtful behavior. Nothing goes unnoticed when it comes to relationships. We have work to do to understand this more fully. Mikey tells me every act has a vibrational component to it. We need to learn how to forgive others and ourselves. Forgiveness ultimately is for us!
Again, Mikey tells me the way we learn best is through experience. What do we do with what we are thrown? How we act influences our spiritual growth from Mikey's view.
(Honestly, I feel we learn something from everyone we interact with, and it can be a positive vibe or a negative one. It's our choice on what road we want to take with any interaction.)
