No, you do not always have to obey your ex, especially if you are no longer in a relationship with them. After a breakup, both individuals are free to make their own choices and live their lives independently. It's essential to remember that breaking up means ending the romantic partnership and relinquishing control over each other's actions and decisions.
If your ex is upset about you not following their rules after the breakup, it's important to recognize that they no longer have the right to dictate your life or actions. You should prioritize your own well-being and happiness instead of feeling guilty about asserting your independence.
Breakups can be emotionally challenging, and it's natural to feel a mix of emotions. However, you should not let guilt or your ex's disapproval control your decisions. Focus on your own growth, healing, and happiness as you move forward. Surround yourself with supportive friends and family who can help you through this difficult time and remind you that you are not obligated to obey your ex's rules any longer.
