So you go out with a girl, have a great time, you have sex, you say how wonderful it was and how fabulous she is. Monday rolls around and you don't call (or email or text) and the big question is WHY? Let us rule out the obvious (he only wants sex)...lets say that isn't the situation, what other reason is there? Do guys really do the 3 day rule? If he doesnt call does it mean anything at all? When a man says he's been busy at work, could he actually just be busy? Do you panic and feel like if you call she will try to whisk you off to Vegas and marry you? What is the deal, men?
