All relationships have 3 areas for each of the parties:
Comfortable, Uncomfortable and Fully Conflicted.
The thoughts, actions, ways of doing, views, risks, uncertainties, priorities are in either of these 3 zones.
For example:
My family member may be comfortable for me to go to meet a friend, uncomfortable for me to go for gocarting (considering the risk element) and maybe fully conflicted for me to go a solo trip to Europe (risk element.
For each thought, action, view, risk, uncertainty, priorities each party can slot it differently. Unless the slotting is clear and accepted and minimized, the conflict can grow.
What messes up this further is the view of the third person about the thoughts, actions, views, risks, uncertainties, priorities of the relationship between the 2 people involved.
E.g.: a spouse may feel that they are being less prioritised when their spouse goes out with friends every weekend. This event may further move from uncomfortable to Fully conflicted as the time goes by.
Relationships are extremely difficult to maintain in comfortable zones with so many views, thoughts, actions, priorities not just of the direct relationships with the people involved, but because it also has to align the 'outside these 2 people involved'.
I think it is a good practice to map the various actions, views, risks and priorities of the close people involved that would be in the 3 zones and discuss with them openly about the agreement to disagree upfront as the conflict may go through frustration and then end up in a 'give up' situation and maybe trying to understand that the other person is different and that they cannot mould them into 'their' ways.
