I can offer some general insights on this matter.
When a relationship ends, it can be challenging for both parties involved. Sometimes, space and time apart can provide an opportunity for reflection and personal growth for both the dumper and the dumpee. In some cases, when the dumpee stops pursuing and contacting their ex, it can create a sense of curiosity or missing presence in the dumper's mind. This might lead the dumper to consider their decision or reevaluate their feelings.
However, there are no guarantees that the ex will come back if you stop pursuing them. Each person and situation is unique, and they may have their own reasons for ending the relationship. It's essential to be prepared for the possibility that they may not come back, even if you give them space.
As for whether the dumpee should reach out and communicate or wait, there is no one-size-fits-all answer. It depends on the individual situation, the reasons for the breakup, and the dynamics between the two people involved.
If you're the dumpee and you feel the need to communicate with your ex to seek closure, express your feelings, or understand what happened, it's okay to reach out respectfully and honestly. However, avoid pushing or pressuring them to come back. Be prepared for any response, which might not always be what you hope for.
Alternatively, you can also use the time apart to focus on your personal growth, heal from the breakup, and invest in self-improvement. This way, you'll be in a better emotional state, regardless of whether your ex comes back or not.
In any case, consider discussing your feelings with close friends or a therapist who can provide valuable insights and emotional support during this challenging time. They can help you navigate the situation with more clarity and objectivity.
