I am so happy to read about your update and how your life is progressing. You have a new boyfriend! How sweet!
Your XH is a real dud for not seeing the real diamond right under his nose. Now his senses are probably dulled by copious amounts of vodka which probably makes his vision hazy and sees OW in a different light. His problem.
As for your vision, have you thought about seeing a low vision specialist. Sometimes they do catch things that a regular eye doctor may not. Want to put this out for you if you haven't thought of this or pursued this avenue.
How sweet!
