>>>i'm not ready to even consider having a relationship right now.

>>>but i don't have any reason to say no to this guy other than that i'm really scared, and i'm going to throw up just thinking about this.

That's plenty reason enough to say no, hun.

AND, you don't even have to have a reason to say no. You are under no obligations to this guy whatsoever!

AND if you do decide to go out with him, you also have the right to change your mind at ANY point in time.

Really truly rooly.
