Love advice???

So, I met this guy. At first I liked him but then idk like I couldn't imagine myself in a relationship with him. Like holding hands and all that. The thing is I told him I like him but I haven't told him I'm like changing my mind. I'm not really a mean person, I don't wanna hurt him but I've been trying to avoid him telling him that I'm sick. Today I come home from school and find a teddy bear and a dog, a card, roses and candies. He wrote really deep things on that card and I'm just shocked. Like he made my day but I don't know what to do. I feel bad. I feel horrible actually. I don't know if give it a shot and see what happens but I'm afraid cause if I end up changing my mind I don't wanna hurt him. HELPPPPP
