Closure is very important. You have to talk about what went on in your relationship. First, talk about the good things that you two had together. Talk about all the positive things that you learned from the relationship. Then, talk about the challenges you had or having. These are the things that you two couldn't agree on a solution. This would help you understand and accept the challenges that you faced. You would now know what you need to work on or avoid in your next relationship.
