You're right @krnel ... Most parents know what it is like to have a discussion like this. As a parent, I have a responsibility to ensure the well-being of my children - and that includes how to interact with my partner (wife).
While children react to conflict or strong arguments from their father in different ways, they are likely to experience fear, worry and anger. If the conflict is extremely intense, they may have emotional trauma, depression and stress, no one feels safe in the middle of an unresolved conflict, especially when the fight is over children, money, sex, separation etc. Their children may feel that it is their fault. In some cases, conflict between parents can have long-term consequences for children. For example, it can negatively affect your ability to form a healthy and trusting relationship with your future partners in the future.
Yeah, a good point is that conflicts need to be resolved, or else they just linger in the background, building up as more conflicts fester and build up... then it's a huge mountain of unresolved things that implode :/
Parents should always reinforce that nothing is their fault with respect to parents arguing. Thanks for the feedback.
