A few weeks ago I rejected someone, but I regretted my decision. A few days ago he wondered if I liked someone (else), and well I actually realized I did like him so I said I did like someone. A day later I told him I actually liked him. He asked me if I wanted to be his girl, and the impulsive person I am, said yes. I haven't seen him since I said that. The last few days I've felt nauseous. I actually get nauseous when I'm thinking about being in a relationship with someone (also hugging, kissing etc.). Also I'm still trying to find the person I am and I'm also pretty young. I just don't think I'm ready for a relationship. What should I do, I don't want to hurt his feelings?
