Recovering self worth after infidelity and divorce

I wonder if you would consider addressing how to manage our mind around divorce (or losing a significant love) to another woman. It seems so many friends in their 40s are going through this.
Not only do you experience a deep pain from betrayal and loss of someone who claimed to love you, but it does a huge hit to your self esteem and self worth as someone else was chosen over you. I have experienced this myself and am reliving it currently with a close friend. In both circumstances, there is this need to seek a new love to replace the empty space or perhaps convince yourself that you are worthy or lovable. Extremely poor choices and desperation in finding someone else are part of this aftermath. I have looked through your podcasts and cannot find anything specific to this common problem. Thanks for your thoughts on how to recover in a healthy way.
