He said "I love you" but now I don't know how to handle the situation?

So I have been going out w/ my boyfriend for a week now (we were dating for 2 weeks prior to that), and last night we were up in my room and were fooling around (we havent had and won't for awhile but lets just say it was a very close prelude to it) and then at one point he said how he loved me and that he knew it was soon and it wasn't because of what we were doing at that moment. Well I didn't respond in the way that i think he would have wanted me to, I kinda just laid there with him and after a couple moments I said how I didn't want my parents to walk in and see us like we were; so we stopped what we were doing and left to go meet up with the rest of my friends for dinner and a movie. The whole time we were out it was like it would feel wrong for me not to feel that way towards him but I can't bring myself to say that to him right now if its not engraved in my heart. So I don't really know what to do now, because nothing else was said about that the rest of the night or at all today, and I feel like its something that we should talk about but I don't know how to go about it. Should it up and talk about it? Any suggestions?
