I have been separated from my ex partner for 17 years. He has been with someone else for this amount of time and has a 14 year old child. I have tried to divorce but he won't . We don't know where he lives this is deliberate. We have contact number.I have a 'live divorce ' from 2020. I used online solicitors who said I have to prove that I have tried to contact him.
