This is my 3rd marriage of 30yrs. I have 4children and 2 stepchildren from previous marriages. My current wife has no children. I brought up 5 of the 6 children. My eldest son was divorced 3 yes ago and was made redundant. This led to him getting heavily in debt. We, amongst other members of the family lent him a large amount of money. He now has a new job which pays well and he has a new partner. He pays child maintenance for his 2 children. He has agreed to pay back the loans in monthly installments but keeps missing the payments with no explanation.
