I do think when people say, "I love you," they do expect the other person to say, "I love you" in response.

Love can be a feeling of warmness, a caring about the other person to the point where you are willing to make compromises and sacrifices, a desire for the person to be happy, and can even be used when the feeling is more lust than a real love.

It is tough when one person says it very quickly into a relationship. How can we "love" in a way that will work for marriage with someone when we don't really know him or her?

Of course, the Greeks had words for all kinds of love. It's unfortunate that we don't have such a variety to explain what it really means.

I agree with Leed that it would be a good idea to talk to him about it. Do you truly at least care for him right now and believe that you can have a future together? The main thing is not to mislead him. That said, there are still countries where marriages are arranged and sometimes the couples do learn to love each other over time.
