Actually, calm down and think about it. Why on earth did you break up?
At that time, the breakup may have been forced by some circumstances, and you didn't think of a better solution at that time. So I chose to break up. I'm sad now because you lost her. A person's strength is often caused by the same personality, which is different in different places. For example, she is very strong and may have a strong smell of gunpowder in her life. She often looks at you and points out your problems directly. But often you will find that this kind of person has a strong purpose, and she can handle anything at home without your help at all.
So think about why we are apart and why we are sad now. To what extent can you accept him?
You are very sad now. If you still have contact information, you can try to contact. If you feel humiliated, you can arrange a chance meeting through a friend's party. See if it's possible to continue.
Finally, I wish you happiness!
I hope it helps you ~ ~
