To add - as long as you`re not going to do anything silly like leap into getting married, or decide you`re going to have his kids, etc - I see no problems with feeling the way you do.
It`s obviously completely possible to feel that you`re in love with someone in just hours - but it will take time to figure out whether that`s just the initial rush or whether it will wear off after some time.

I once felt very much like I was in love with someone. He also liked me, and it seemed like it could sprout into something amazing.
Then we went on a trip together... And I realized somewhere along the line that it wasn`t love, just deep interest and strong friendship, and the cloud of uncertainty and potential passion simply dissipated.
There was no horrific "Road trip!" nightmares, or really anything bad at all - it was a great trip and we had tons of fun. But it was friendly fun, and I think we both realized that it wasn`t something that would last if it progressed any further. We`re still friends now.

With my husband, I knew he was the one, and he wasn`t even interested in me (had a huge crush on a girl he worked with, and was trying to get closer to her). We went out a few times, got along really well, had some fun... And then he made the choice to continue pursuing the girl at work. And we went our separate ways. I went home, and that night he called me, said he`d given it a lot of thought, and had come to the conclusion that the safety and happiness he felt with me was truly love - while what he felt about her was nothing more than a crush that would likely be gone if they were together... And he wanted to choose love.
We ended up moving in together a month or so later, and have never looked back.
