I want to get my ex-girlfriend back. Is there a kind person who can explain to me in detail how to save it?

Well, I don't know what's wrong with you, but according to the news, she is rejecting you now.

My advice to you is not to disturb her for the time being. Your eagerness will scare her and disgust her. If you continue your current behavior, it will only make her farther and farther away from you. If you want to get her back, send her a text message and tell her that you love her, but you know it has caused her harm and trouble. You will give her time to consider whether she is willing to give you another chance. Don't answer now. Everybody calm down.

Then you really need to control your behavior and consider whether you will really change yourself for her, if you really have this determination. You should know where your contradictions are and get rid of them. Not with your mouth, but with your actions. In addition, if you just have different ideas, you should calm down and work hard to make money, let her see your efforts, let her feel your sincerity and feel that living with you will be very happy.

Of course, I can't guarantee that she will change her mind by doing so. But your life will get better and better. Maybe she didn't choose you in the end, and another good girl took a fancy to you. But it kept haunting her. Wasting your life will also make her more and more determined to leave you. I hope you can be happy.
