What you need to ask yourself when this happens is: Do you consider a wonderful relationship one in which your partner lies to you? Is being lied to by a liar your idea of love and respect? When you are emotionally involved with someone, it is not always easy to ask and answer these logical questions. You often will make excuses for a liar, just to make yourself feel better about staying with someone who does not truly respect you. When your partner lies to you, it is because he does not respect you and is not as committed to the relationship as you would like to believe. Of course, there are different kinds of lies- little ones and big ones, but a lie is still a lie, no matter the size or reason for the lie. Look at it like this: if your partner can lie so easily over little things that are unnecessary to lie about, then you can be pretty sure that he/she will lie to you about bigger things that will really matter and damage the relationship.
