Whether or not it is "wrong" to continue being responsive, respectful, kind, and polite to an ex who treated you poorly depends on your individual circumstances and feelings. There is no one-size-fits-all answer to this question, as each person's situation and emotional response will differ.
Here are some points to consider when deciding how to interact with an ex who mistreated you:
Emotional well-being: Prioritize your emotional well-being and mental health. If interacting with your ex in a polite manner helps you maintain your own sense of integrity and inner peace, then that may be a valid choice for you.
Boundaries: Establish clear boundaries and limits in your interactions. Being polite doesn't mean you have to tolerate disrespectful behavior or allow your ex to manipulate or hurt you further.
Closure: Sometimes, being civil and respectful can help bring closure to a chapter in your life and allow you to move on more gracefully.
Letting go: Responding with anger or negativity might not bring you the satisfaction you seek, and it could prolong feelings of bitterness or resentment.
Self-respect: Displaying kindness and respect even in the face of mistreatment can be a reflection of your own strength and self-respect. It shows that you are not allowing their actions to define your character.
On the other hand, tough love and not responding may be suggested to protect yourself from further emotional pain or manipulation. It can also help create distance and space to heal and move on.
Ultimately, the decision is yours to make. Take time to reflect on your feelings and consider what will be most beneficial for your own emotional well-being. If you find that continued contact with your ex is causing more harm than good, it might be necessary to set stronger boundaries or limit communication. Surrounding yourself with supportive friends, family, or even seeking professional counseling can also be helpful in navigating through difficult emotions after a breakup.
Remember that there is no right or wrong way to handle a breakup, but prioritizing your own well-being and growth should always be a top consideration.
