First thing my dear, it depends on you what meaning do you take from your life. Your ex may make you not trust anyone else again. But, think about it, thats the main reason you should trust someone else. Because, you skipped one untrustworthy person in your life. Now you have more chances that you would find someone trustworthy. Really, now you would understand the meaning of love and trust in a better way :)
Second, there is a term in japanese called "Kintsukurai" it means golden repair. Item gets more precious after being broken and repaired.
