When you and a loved one have a deep disagreement can your relationship endure?
The answer is yes and no--it's not one way or the other as it depends on what the disagreement is about and how that affects the lives of those involved.
If the disagreement lies within the range of safety, health, and humanity, differences of opinion may signal the end to a relationship. For example if a loved one is acting in ways that jeopardize your safety or well being, you will have to cut ties or risk grave circumstances. Sometimes, people can change and those who were once a grave threat can adopt better, more humane behaviors and then regain entry into your life, but while people are a danger to you or others, there's no other choice than to sever ties.
When the disagreement lies within the range of procedure and does not affect health, safety, or humanity in any grave way, you may simply agree to disagree or compromise in ways that saves the relationship. Most of us with good relationships are familiar with this kind of compromise and in time we realize that to compromise with regard to procedure usually becomes a non issue in time while the more important aspects of the relationship stay strong.
Disagreement is apart of any good relationship. When we know and care about someone intimately, we will be willing to disagree for all kinds of reasons and to maintain a good relationship. It is always sad to end a relationship due to unhealthy, deep disagreement, but it would be much worse to sustain a relatioship that is harmful to you or others. Onward.
