Loss of trust

I am a nice person and I always try to help my friends. I am happy to do that, because when I help somebody, I feel good about myself. But, there is this one friend who is really starting to get on my nerves. You see, he is a gambler and he often loses all his money on those stupid slot machines. As a result, he often asks me to borrow him money, but I do not trust him anymore. That is why I always tell him to contact the best money lenders in the area. They have already helped him a couple of times.
