Re: seperation
I'm not trying to start a fight but there seems to be a fair amount of ancedotal evidence that men are disadvantaged in the courts when seeking custody of their children. BTW, cases are held in camera.
You should think about consulting a solicitor, if for no other reason than securing an adequate pension for yourself.
Your family is going through a major change in your lives and you may not be emotionally able to think about your future. It may cost a lot but I think it's important to have an impartial expert (solicitor) in your corner advising you on your future.
