I am 17 now, and started dating this one fellow when I was fifteen. At the time he was 44. Of course, now he's 46, but that's not really the point. He's divorced and has two kids, one son 2 years younger than me, and a daughter the age of my own younger sister (12). I look after them for him sometimes. I feel like I really love him, but I don't really feel the same way about him....
