Don't expect him to put in any effort.
Don't expect him to stay interested in you for more than a few weeks (or a few days…or hours).
Don't say "I love you", don't even say "I like you" as that makes them mad or annoyed or something.
Don't expect him to understand that your need of physical space doesn't mean you're not attracted to him.
Don't ever mention anything that may ever be taken in the least bit negative about yourself.
Don't expect him to not hurt your feelings and actually realize it.
Don't expect him to understand why/how he hurt your feelings.
Don't tell him your week was anything but good, even if it was horrible.
Don't expect him to try very hard for you, you'll be doing all the work.
Don't think you have any right indicating your facial hair preference.
Don't expect him to care about you as much as him.
Don't actually think he would ever actually date you, be in a relationship with you, and DEFINITELY don't think he'd ever want to sleep with you, especially if they know they'd have to wait. Hell, don't even think he'd want to ever kiss you or even hold your hand.
Don't think he'd actually tell you he's not interested—he'll just stop talking to you and hope you get the hint.
Don't think him enjoying the first date and agreeing to a second actually means he wants to go on another date. Or that him saying he'd date you is true.
Don't automatically believe anything. Everything is a lie until proven true.
Don't let him get to know the real you.
Don't discuss any problems you may be having…everything must be 100% positive at all times.
Don't automatically assume that he isn't using you to get back at his real girlfriend.

I do agree with a lot of yours though as well. These are just the ones that apply more personally to me.
