My partner doesn't see his kids and hasn't done for 8+ years. They are both adults now.
Only contact he has is by email. They refuse phone calls etc.
Every time they email they ask for money. If he doesn't give it they emotionally blackmail him with a sob story. They stories get worse and worse if he doesn't pay up.
It's heartbreaking to see the affect it is having in his mental health. He gives in as he is frightened that they will commit suicide if he doesn't.
Btw he already helps them out monthly and was and was always very generous to his ex with maintenance payments etc.
What would you do if you were me? Oh and they don't know about me as that would be another reason for them to abuse him.
(It's not £50 they ask for but hundreds and sometimes thousands)
