Should I try to repair it?
Since you have chosen to give up, don't be forced, especially since he has a new life. You just haven't found the right fate yet, so you will feel a little unacceptable that he has a girlfriend. Maybe I was wrong. But I hope you can give up the idea of redemption. You will meet the right boy at the right time. Your conditions are very good. If you have to save it, you need to consider the consequences, your parents, and whether you can really accept a man whose job is not as good as yours in the future.
