Please dont pay the mother in cash, that is just a waste of hard earned money. Pay the service provider(s) yourself, at least then you are sure it goes towards what it is meant for.
I am taking care of my children, everything including medical fund, school fee, transporting etc. etc. The father is not interested in seeing either of the two children, as he always has a way of getting around a possible visit. However, I'm getting maintenance and extra for taking care of a special needs child. Married again, but we are struggling to keep going. I dont milk the cow, therefore I have the convenience of asking if anything more is needed (which I rarely do).
Dont have any respect for a divorced parent (mother or father) that milks the cow as much as possible, that is disgusting.
