以下是引用shanshan00在2008-1-30 17:46:00的发言：
还有个条件， SEX前他怎么都有空， 几次SEX后他忽然变成很忙， 那就是他不爱你。if a guy is into you, he will drop anything to spend time with you, regardless of how busy he is.
if a guy is not into you, he will make up all kinds of excuses to not see you.
the truth of the matter is, often we fall for guys that don't feel the same about us, and vice versa.
