Don't save up all your little dislikes and peeves to hit your guy with it all at once.

Guys aren't mind readers, even if it seems that way in the movies. If you don't communicate what you want from us, chances are you're not going to get it.

Know what you want, and if you don't know, don't pursue anyone till you do know.

If you confide in people but not your guy you'll get nowhere.

Don't base life changing decisions on emotion (seems impossible but try!)

Don't build a guy up for 4 years then break up because of a "what if" (I got the wonderful "what if there's another person that i'm meant to be with?" nonsense.) T_T
