How Do I Avoid Hurting Him?

Right guys I have nobody else to talk to about my love life. So here goes...

I went on a date with this guy and he was VERY kind to me. He did everything right, set out his intentions and I could tell that he really liked me. When I wanted to leave, he kept pushing for extra time and kept taking random photos for memory. He insisted on buying me more food and he was too nervous to eat around me.

So the issue is I really don’t want to hurt this guy but I just wasn’t feeling him. He’s a lovely guy but he’s just not for me. What do I do? And what do I say? When do I say it? I don’t want to crush him he was so excited to be with me.
