You must have been troubled by when to say "I love you" because it is one of the greatest puz-zles in our life．
What if you say it first and your partner doesn&39; t love you back？ Or if they do say it but youdon&39;t feel they mean it？ Being the first to declare your love can be nerve-racking(紧张) and riskyand can leave you feeling as vulnerable as a turtle with no shell．But is the person who says it firstreally in a position of weakness？ Doesn&39;t it pay to hold back, play it cool and wait until the otherhalf has shown their hand fh&39;st？
"A really good relationship should be about being fair and being equal," says psychologist Sid-ney Crown．"But love is seldom equal．" All relationships go through power straggles but, he says,if a love imbalance continues for years, the rot will set in．"That feeling of &39;I&39; ve always loved youmore&39; may be subverted(颠覆，破坏) for a time, but it never goes away completely and it often e-merges in squabbling(大声争吵)．" In love, at least, the silent, withholding type is not always themost powerful．"The strongest one in a relationship is often the person who feels confident enough totalk about their feelings," says educational psychologist Ingrid Collins．Psychosexual therapist PaulaHall agrees．"The one with the upper hand is often the person who takes the initiative．In fact, theperson who says &39;I love you&39; first may also be the one who says &39;I&39;m bored with you&39; first．" Hallbelieves that much depends on how "I love you" is said and the motivation of the person saying it．
"Is it said when they&39; re drunk？ Is it said before their parmer flies off on holiday, and what it reallymeans is &39; Please don&39; t be unfaithful to me&39; ？ By saying &39; I love you&39;, they really saying&39; Do youlove me？&39; If so, wouldn&39; t it just be more honest to say that？" Collins agrees that intention is every-thing．"It&39; s not what is said, but how it&39; s said．What it comes down to is the sincerity of thespeaker．"
