Keep in mind that people are complex, and individual circumstances can vary. Here are some possible reasons:
Emotional Rollercoaster: Breaking up can be emotionally challenging, and the person blocking and unblocking you might be going through a rollercoaster of emotions. At times, they might feel the need for space and cut off contact (blocking), but later, they might miss you or feel guilty about cutting ties (unblocking).
Indecisiveness: Your ex may be unsure about the breakup and might waver between wanting to maintain some connection and wanting to move on completely. This uncertainty could lead to the cycle of blocking and unblocking.
Control and Attention: Blocking and unblocking someone can be a way for some individuals to gain a sense of control or seek attention. By blocking you, they might hope to provoke a reaction or make you feel anxious. By unblocking you, they may be seeking reassurance that you still care about them.
Healing and Closure: Some people block their exes as a way to cope with the breakup and focus on healing themselves. Later, they might unblock you, hoping that time apart has helped both of you move on and find closure.
Checking Up on You: Your ex might block you to limit their exposure to your life, but then unblock you to occasionally check up on how you're doing or what you're up to.
Immaturity: Blocking and unblocking could simply be a result of immaturity or impulsiveness. They might not fully understand their emotions or the impact of their actions.
Influence of Others: It's possible that friends or family members of your ex are influencing their decisions. They may encourage blocking when emotions are high and unblocking when things have calmed down.
Ultimately, this behavior can be confusing and potentially harmful to both parties involved. If you find yourself in this situation, it's essential to prioritize your well-being and consider setting boundaries. If you can, try to have an open and honest conversation with your ex to understand their perspective, but also be prepared to respect their decisions if they need space or distance. If the cycle continues without resolution, it might be best to focus on your own growth and healing apart from the situation.
