When is it too soon to tell someone you love them?

I’ve been talking to this guy for a couple of weeks,& met him on Friday, we clicked really well, and I’m more comfortable with him then I ever been with anyone before. But we’re not “officially” dating. It seems like it thou. And I’m enjoying it. But he told me Saturday night before he came over that he loves me.. I don’t know if it’s ‘love at the first sight’ type of thing. Or he’s just trying to make me feel good or whatever. Even he says it’s too soon but he wanted to tell me it anyways. I really like this guy.. he makes me feel amazing. Any advice?..
