The big L word: HELP!!

So I've been with my boyfriend for almost 8 months now. And it's been absolutely great. We don't fight at all, and he's the sweetest man to me. I'm 19 and he's 22 (almost 23) and I said I love you first (which I've never done) and he didn't say it back, talk about awkward. But anyways I've backed off with that because it really hurt my feelings that he didn't feel the same way about me because I had an awful relationship prior to ours, and I'm scared to get hurt again. And I don't want to press him to say it if he doesn't mean it. But I also don't want to waste my time at this point for him to dip out because he doesn't love me. I know he has strong feelings for me, he's made that clear. But my main question is if it's normal for me to be worried about this? Or am I just over reacting. Should I try and talk to him about it?
