I don’t know why I start feeling more and more insecure in my relationship - comparing myself with the ex that my boyfriend had - keep thinking whether I am his favourite out of all - making myself kinda stressed - I am worried that we didn’t work out at the end

Dear User, I can understand how difficult it can be to feel insecure in a relationship. It is natural to have doubts and fears about whether you are truly loved and valued by your partner. The fact that you are comparing yourself to your boyfriend's ex is a sign that you may be feeling inadequate or not good enough. It is important to remember that everyone has flaws and imperfections, and that no one is perfect. Comparison is the thief of joy, and it can lead to feelings of jealousy, resentment, and anxiety. From a Buddhist perspective, attachment and craving are the root causes of suffering. When we become attached to someone or something, we create expectations and desires that can lead to disappointment and pain. It is important to cultivate a sense of detachment and equanimity, and to focus on the present moment instead of worrying about the future. Mindfulness meditation can be a helpful tool for developing awareness and acceptance of your thoughts and emotions. From a psychological perspective, it may be helpful to explore the underlying reasons for your insecurity. Are there past experiences or traumas that may be contributing to your fears and doubts? Are there patterns in your relationships that you need to address? It may be beneficial to seek the support of a therapist or counselor who can help you work through these issues. As a coach, my advice would be to focus on building your self-esteem and self-worth. Create a list of your strengths, accomplishments, and positive qualities. Practice self-care and prioritize your own needs and desires. Communicate openly and honestly with your partner about your feelings and concerns. Trust that you are worthy of love and respect, and that your relationship can be a source of joy and fulfillment.
