I've been looking for this title for some time and came across the following link to an on-line catalogue from a company called 3DD Entertainment Ltd in London.
Here's the blurb:
"SEPARATION concerns the inner life of a woman during a period of breakdown - marital and possibly mental. Her past and (possible?) future are revealed through a fragmented but brilliantly achieved and often humorous narrative, in which dreams and desires are as real as the London of 1967 (complete with Procul Harum music and a Mark Boyle light-show) of the film's setting."
