Thanks for all your replies.
Yes, I do have a child from this marriage that was born in this country, but now an adult who has left home. The advice I was looking for was more on the practical aspects of returning to the UK. Where could I live? If I would be entitled to any benefits? What would happen to my pension, as I am now fast approaching retirement age? How easy or difficult is long distance divorce? Is divorce possible from the UK when I have married in another country?
So many daunting questions, I don’t know where to start. I will need to leave with just a suitcase, leaving behind so much.
