I think that understanding and compassion are certainly non-negotiables for any relationship I participate in, but owed? Especially in the context of what I've written, it falls into the same category. It's certainly not always willingly given, so I wouldn't say it's owed. I would just say that if it's not willingly given then you can exercise your right to be done with the relationship.

Have your parents both passed? Maybe they're together somewhere :)
