I, too, had parents that helped me. I always felt guilty, too. It wasn't until later in their lives that I was able to help them. When their health started to fail I was all they had to help out. Don't worry, your father does this because he loves you. You will one day have your chance to repay him by being there for him when he needs you. Let go of the guilt. What is given out of love should not cause guilt. It's not what he would want.
