I'm going to take a different position. I think you are expecting too much too soon. Until you have an agreement that the two of you are exclusive, he is free to do what he wants, and so are you. Besides, you've only dated him a few times. You shouldn't be expecting ANYTHING at this point.
There is a difference between casual dating and serious dating that lots of people have a hard time distinguishing between these days. You might want to contemplate that.
Oh yeah - I'm not a guy, so feel free to disregard my advise.
