Given the above summary, write a detailed text in English for it.
Determine a set amount of time where you will no longer interact with your ex. This includes phone calls, text messages, social media, and in person meetings.  You are not to initiate contact or respond to her at all. This will give both of you space to heal and work out your feelings.  The no contact period is typically 21, 30, or 45 days.  Whatever period you choose, you must stick to the plan. No contact will give both of you time to heal and also give your ex-girlfriend time to miss you. If the relationship ended badly, this period will allow both of you to cool off and work through any negative feelings. Even if you no longer talk to your ex, seeing pictures of her and knowing what she is doing will make you want to contact her.  Constantly getting updates about her life through social media will make things more difficult for you.  You also may find out information you do not want to know such as she is dating someone else.  If you need to unfriend or block your ex-girlfriend on social media, then you should. You do not have to let your ex-girlfriend know that you are taking these steps. Do not post how sad or depressed you are about the breakup either. Since you are no longer talking to your ex, you have time to think about the relationship.  Consider the pros and cons of the relationship.  Think about the things that you did well and things that you did not. Also, think of the things you can do differently if you get another chance with her. It may be helpful to write a pros and cons list down on a piece of paper.  This will also help you think about the relationship. You want to be the best version of yourself you can be.  This will make you more attractive to your ex when you contact her again. Eat healthy and exercise.  Spend time with friends and family who love you. Do activities that you not have had time to do when you were in a relationship such as volunteer, play video games, read, etc.  It's also fine if you do not feel like going out a lot or being social.  Do whatever you need to do to...
