There are so many different ways to look at a relationship. Many of us get trapped in the “right now.” Right now you might not like each other very much. But how about in the future? Your current issues are probably situational. What are your goals/dreams? Do they include him/her? Do their dreams and aspirations include you? If your dreams align together, it’s a good sign that you do indeed need to save the relationship. Working on supporting one another to accomplish those dreams. All about the big picture!
The fact that you are asking this means it’s something you are interested in doing. Saving your relationship, that is. If you were completely checked out, this option wouldn’t be at the top of your mind.
