girlfriend was raped

My girl friend was raped a few months ago. I'm not bothered by it because I know she didn't want it. The issue is that she is pregnant and wants to keep the child and wants me to father it. I'm only 17 and will be graduating this coming may and going to college. The two of us had already planned to not have any children until we were both through college and have been sticking to this. Now I'm expected to drop all my whole life to take care of this child. I have talked to her about this and tells me things happen and we have to adjust but Im just not ready to be a parent. What should I do? Tweet
