Before you can answer that question, there are three important aspects of your relationship to think about. First, do you trust each other? If you have trust then, you believe they are honest and truthful to you, wouldn’t hurt or deceive you and have your best interests at heart.
Next, are the two of you similar in underlying key life values? Do you think similarly when it comes to those values that are most critical to you and your life, like the importance of religion, family, or health?
And lastly, how do the two of you handle stress and conflict together? You want to handle your disagreements and stress in a positive, constructive way. If all three of the previous qualities are present in your relationship, then it’s at least worth trying to see if you can save it.
