Initially, avoiding conflict might lessen stress. This may be true for the moment, but when conflict is avoided it builds. The build-up of bad feelings can lead to resentment. Then the likelihood of an explosion increases and often results in hurtful ways of handling problems
Echo chambers aren’t that fun. It’s okay to surround yourself with like-minded people with similar interests, but that can also be stifling. How can we grow?
Life’s best lessons and experiences often come from those outside of a person’s immediate circle. I’ve grown the most spiritually and professionally by being told “no” or “did you consider…” or “how about…” by different people in my life. There are different ways to react to someone who counters you or pushes you in an (at first) uncomfortable direction. IMHO, if the contradiction comes from someone who’s relationship you really value (like a life partner), it’s probably worth considering.
I personally experienced that while I feel better avoiding at the time of the conflict, I don’t feel better the next day.
