Whether it's right or wrong to continue being responsive, respectful, kind, and polite with your ex who treated you poorly is a subjective matter. It depends on your personal values, emotional boundaries, and what you believe will bring you the most peace and closure.
Some people might argue that maintaining a friendly demeanor towards someone who hurt you can be a sign of emotional maturity and strength. It shows that you are not letting their actions define your character and that you are choosing to rise above the negativity. Additionally, being respectful and polite can create a more amicable environment, which may be important if you have shared friends or other connections.
On the other hand, others might advise you to show some "tough love" or distance yourself to protect your emotional well-being. Keeping contact with someone who has betrayed you can be emotionally challenging and may prolong the healing process. Setting boundaries and limiting contact can be a way to prioritize your own emotional health and prevent further hurt.
Ultimately, it's essential to prioritize your own feelings and well-being. If continuing to be responsive and polite feels empowering and helps you move on, then it might be the right choice for you. However, if it feels draining and causes you distress, it might be time to consider distancing yourself and focusing on your own healing.
It's essential to remember that there's no one-size-fits-all approach to handling difficult situations like this. Take some time to reflect on what is best for you and seek support from friends, family, or even a therapist to help you navigate through your feelings and make the best decision for your emotional health.
