Gigill You may have felt you made a mistake but that may not be the case for Sophie. She is recognising her problems and thinking about her options.

I chose to leave my marriage and it was complicated but I prepared for it by developing my own independence. No it was not easy but it was the best thing for me and my children.

There is a world full of people that you can have relationships with of so many different kinds, having fun, helping and supporting others, clubs, charity work, shared interests, using your expertise to help or just listening to others who need someone.
