@Pitter,
Of course the nineteen year old girl wants only economic support because this is the age when we want to have all you can see in the markets, clothes, cars, new and expensive phones etc and she likes herself in this position as she has all she wants . That forty years old man sees her just as a sex partner and he believes that if he asks a favor he must return the favor...with money, of course.
I still think that the problem is in that man's wife, because at this age women are too busy with children, with work, cleaning house or something like that and she doesn't pay too much attention to her husband like in her 20's. Because she has other important things to focus at. I don't blame his wife, I blame him, because him must understand that she is too busy to pay him attention and he must to try hard to relax her and to amuse her as much as he can....
