Adapting to change can be a shock to the system, and It takes time. You can't set a timetable – everyone adapts differently – but usually a few months or a couple of years are enough for someone to start living comfortably with 'the new reality', and re-building a life. In this case, it's a divorce, but whatever the change, we all manage the process in our own way. It helps to have insight, to be honest with oneself, and to accept. But occasionally people get stuck. It's a doubly painful when they don't even realise it.
