I can offer some general insights that might help you understand potential reasons for such behavior:
Communication Issues: Some people struggle with effective communication and may find it challenging to express their feelings or intentions openly. Instead of having a difficult conversation about ending the relationship, they might choose to avoid it altogether and resort to blocking and unfriending as a way to detach themselves.
Fear of Confrontation: Ending a relationship can be emotionally challenging for some individuals. They may avoid confrontation and difficult emotions associated with breaking up by simply cutting off contact.
Emotional Immaturity: Emotional maturity varies among individuals, and some people might not know how to handle relationships in a healthy and respectful way. This can lead to poor treatment of their partners when things get complicated.
Personal Issues and Baggage: Sometimes, a person's behavior is influenced by their own personal issues and past experiences. These issues might have nothing to do with you, but they can impact how they behave in relationships.
Changing Feelings: While you may have been a great girlfriend, feelings and emotions can change. Your ex might have experienced a shift in their feelings or priorities, leading them to end the relationship abruptly.
External Factors: It's possible that external factors in your ex's life, such as stress, family issues, or work problems, contributed to their behavior.
Seeking Closure: Blocking and unfriending can be an attempt to create distance and move on without facing the emotional challenges that come with closure.
Remember that everyone has their reasons for their actions, and it's not always easy to understand them fully. It's essential to focus on your well-being and healing after a breakup. Surround yourself with supportive friends and family, engage in activities you enjoy, and consider seeking professional support if needed. Give yourself time to process your emotions and eventually move forward.
If you find it challenging to cope with the situation or the emotional impact is overwhelming, don't hesitate to reach out to a mental health professional who can offer guidance and support tailored to your specific situation.
