“Sweet” jealous is when ....

• ...a guy feels a tinge of jealousy when he sees you enthusiastically hug your platonic guy friend.
• ...a guy asks you where you are.
• ...he jokingly tells you to have fun without him and frowns when you leave.
• ...he asks who is on the phone or who texted because he is sincerely curious.
• ...he tells you that your guy friends should be jealous of him for being with a great girl like you.
• ...he gets slightly possessive — like putting his hand on your lower back or arm around your shoulders — when another guy checks you out.
• ...he checks out your Facebook page or Twitter feed to see what you’re up to.
• ...he playfully asks if some of the fabric is missing on your miniskirt (a la Daniel Cleaver in “Bridget Jones’ Diary”).

“Crazy” jealous is when ...

• ...when he guilt trips you for going to a bar without him because obviously you are going to have sex with other dudes there.
• ...he asks where you are and shows up there unannounced to check up on you.
• ...he tells you to have fun without him and means it in a passive-aggressive, whiny, why-would-you-ever-want-to-hang-out-with-anyone-but-me? way.
• ...listens in on your phone calls or reads your emails or texts.
• ....he implies the only reason your guy friends want to spend time with you is to try to get you in bed.
• ...he punches a guy who checks you out.
• ...stalks your Facebook or Twitter pages and asks you questions about all the dudes who write on your Wall or at-reply you.
• ...gets into an argument with you about how your outfit is “skanky.” (Hello, control freak! I’m dumping you in five ... four ... three ...)
