I do feel sad for what has happened between him and Carol, but at the same time, I can understand it. I did leave my ex-wife, and we are divorced now. She remarried about 5 years ago, and I am happy for her that she was able to find another man. I can only say that I am praying for Sir Edwin and also for Carol and their family.
