Could he be interested in getting to know me?

A guy I met last Friday added me on Facebook on Sunday. I just got back from being away for the weekend and accepted him. We both kissed and talked that night, and we stayed over at a house with other people (mine and his friends & a mutual friend of ours) We ended up sharing a futon on the floor and kissing more, and sleeping together (no sex). We didn't swap numbers, but he kissed me and said see you soon. I didn't think we'd talk again, but is it possible he likes me a little?
