I've known this girl for 3 years, we where never supposed to be in a relationship she was just too young for me. She has a drug problem and when she got in trubble for it she started to talk about a serious relationship. I practically begged her not to go there, and that I whould help her anyway. Now that she is about to go into treatment I find my self sick to my stomach. I know that when she is done getting what she whants and needs from me that she will probably move on, and I hope if she dose, she finds a guy closer to her own age that isn't the kind of guys I've seen her with over the years. She already has started to show signs that she is having doubts about what she said 6 months ago. I've been though this kind of thing several times before. And I was ok with it. So why do I feel physically sick over this?
