For a relationship to be happy and healthy, you don’t always have to think alike. Each of you have your own perspectives and ideas based on your unique personalities and background. It is not possible that you will always think alike.
It may be simpler if you did think alike, but then you’d be missing out on so much. Your differences expand your worlds; you get to see other ways of looking at things. You come to bigger and better ways.
When you encounter a difference of perspective, it is important to think together. Each of you put your ideas down, maybe gather some other perspectives and then think together to come up with a resolution that works well for the situation.
When you value the thoughts and ideas of others, you can accomplish more and bigger than you ever could do on your own.
