THE X-FILES star Gillian Anderson insists she was to blame for the collapse of her 18-month marriage, because she is too hard to live with. The Canadian actress split from her second husband, documentary film-maker Julian Ozanne, in April (06), but has already moved in with new lover MARK GRIFFITHS. And the 37-year-old has had to change her personality in the hope her new relationship will have a happy ending. She says, "I'm incredibly strong willed and like to do things my way and when you're trying to cohabit with someone or to parent a child, those aren't always good qualities. "There needs to be more space and time, and a willingness to hear other people's ideas and do things their way. I have to work on that."
