I can only provide general insights.
Whether your ex-lover loves his new partner more or less than he loved you is difficult to determine from the outside. Love is a complex emotion, and comparing someone's feelings for different people is not straightforward. People's experiences and emotions can change over time, and their actions may not always accurately reflect the depth of their emotions.
It's essential to recognize that relationships are multifaceted, and they depend on various factors, including emotional connection, compatibility, trust, communication, and personal growth. People may have different reasons for their actions, and sometimes individuals make choices that don't necessarily indicate the intensity of their emotions.
Instead of dwelling on whether he loves his new partner more or less, try to focus on your own healing and growth. Moving forward after a difficult breakup can be challenging, but it's crucial to prioritize your well-being and happiness. Comparing yourself to his current partner or dwelling on the past may hinder your own progress.
Remember that you deserve to be in a relationship where you are treated with love, respect, and loyalty. Take the time to understand your feelings, learn from the experience, and use it to shape a healthier and happier future for yourself. Surround yourself with supportive friends and family, and consider seeking professional guidance if you find it challenging to cope with the aftermath of the breakup.
