Anyone can, Tiggs, that's the point. You just have to look forwards, not backwards.
I had some excellent advice at the time from friends, the GP, etc and it really helped me to focus. My confidence grew and I really became happy again. When I started dating again I had the sense and the confidence to walk away from anything or anyone that wasn't good for me and never feared or hated being single. I waited patiently and Mr Right eventually came along. I wouldn't have "settled" under any circumstances.
