A reader writes in: "I have cut a sibling out of my life. How can I come to a resolution that I accept and feel good about without having to deal with that other person?" Perspective is the answer. Some people come into our life for a reason and some for a season. No relationship is really forever. Some relationships are not worth the time and energy they take from you and leaving is a valid choice.
On the other hand if you are not feeling good about this rift in your family, maybe there is a part of you that would rather have it another way. If you look at the bigger picture of the world in conflict, of countries threatening each other, of one group mortally hating another group, it really comes down to the same principles that happen between individuals. When people feel a need to be right that they are wronged, it perpetuates conflict. Peace as a collective begins with peace as individuals and each one of us counts.
Having the ability to make peace is a great skill to have as a conscious communicator. The ability to get past differences and polarization will serve you in many interactions. This situation can be an opportunity to develop your communication muscles in that regard.
