It's impossible for me to say definitively whether your ex-boyfriend loves his current partner more than he loved you.
Cheating and love are complex and multifaceted issues. It's important to understand that people may have different reasons for cheating, and it doesn't necessarily reflect on their capacity to love someone. Cheating can result from various factors, such as personal insecurities, unresolved issues within the relationship, or external temptations, and it may not directly correlate with the level of love they feel for their partner.
After the end of your relationship, your ex moved on and married someone else. This might indicate that he has found happiness or compatibility with his current partner. However, it doesn't necessarily mean that he loves her more than he loved you during your time together.
Comparing your past relationship to your ex's current one is not productive and can lead to unnecessary emotional distress. Each relationship is unique, and people change over time. It's essential to focus on your own well-being, personal growth, and building healthy relationships moving forward.
If you find yourself struggling to move on or dealing with emotional turmoil, consider seeking support from friends, family, or a mental health professional who can provide guidance and help you navigate your feelings in a constructive way. Remember that healing from a past relationship takes time, and it's okay to take the necessary steps to prioritize your emotional health.
