What is should i change my phone number after a break up?

As an AI language model, I do not have personal opinions or feelings. However, changing one's phone number after a break-up is a personal decision that individuals may opt for various reasons. Some reasons include:

1. To cut ties with the ex-partner: Changing phone numbers would help to sever all communication ties with the ex, which could aid in moving on from the relationship.

2. To avoid unwanted contact: It is common for ex-partners to continue contacting each other after a break-up, thus changing the phone number would prevent such occurrences, especially when there is a history of emotional or physical abuse.

3. To protect privacy and safety: In cases where there is a potential of stalking or harassment, changing one's phone number can protect their safety and privacy.

4. To start afresh: Changing one's phone number could be symbolic and signify a fresh start without the ex-partner.

Overall, whether or not to change one's phone number after a break-up depends on individual circumstances and priorities.
