I always knew in my heart of hearts that my ex could not be relied upon if some health catastrophe ever happened to me. A terrible thing to think about your husband of 24 years but true. And now that all three of our children in their twenties have mental health issues, he is proving to be pretty useless there as well. He doesn't cope well with the disappointment of having imperfect (but wonderful) children.
The great thing for you is, your future is wide open now. You can get out there and take risks, do things YOU want to do without your ex's negative comments on your ambitions.
This has been the biggest positive from my divorce. I am doing work I love, and have made a big enough name for myself that I am invited to lecture to other physicians. I learned to play the drums at 53, then a little vibraphone and glockenspiel. My best friend, a professional singer songwriter, had me play on her latest album and just begged me to join her for part of a tour opening for a famous band from the 80's. I've written a chapter in a medical book and would like to write more.
None of this would likely have happened if my ex had stayed. This isn't the life i expected, but in some ways, it's better. If you throw off the shackles of doubt and just get out there, great things can happen. We women are at the height of our powers at this stage in life!
