Thank you for sharing your story with me. I am going through that exact situation. My wife's boss is also 25 years older than she is. She gave me the ILYBIDLY speech, and has refused to look for a new job.
I've begun getting my life in order, and am trying to focus on becoming the best "me" I can.
Yesterday was tough (first day of no contact/going dark), but am so glad I made it through. I'm scheduled to go to the car dealership Saturday to trade in my SUV for a smaller, less expensive car (really trying to get finances in shape before/in case the divorce is sprung on me).
I also registered to go back to school this Fall, which is something I've been wanting to do for a while. Hopefully day 2 goes easier. I know I have a long road ahead of me, but between the immense sadness and anxiety, I do have sporadic moments of hope for the future. Trying to focus on that
