Oh Peter, I feel for you. I have two friends who just can't get over their exes and be there with new people. Maybe it's a fear of rejection or the potential for hurt in a new relationship. Therapy has helped me with my memories. Good luck on getting vaccinated!
Thanks so much, Ahona. Sorry to hear the man child is a multi-generational thing. (And the comments...I know!)
Thank you John. Good point about being open-minded.
