I don't know. Maybe making out with him is outside of your comfort zone. It's cool that he respected boundaries that you set. But it sounds a little like you aren't ready for that stuff, or especially aren't ready for it with a guy that much older. 4 years, or whatever, isn't that big a difference when you get a certain age, but it is a big difference for you. He's in a different stage of life. As far as being a thing. He's only around a few days right? Then what? Skype. I think you can still skype with him and all that and not be a thing, still be friends.
