Do people lie to draw someone closer?

I don't think so. Most people do. It's kind of dumb to lie about that though. I know my family loves my boyfriend so I don't think it's an lie.

Of course people can do that but I had a ex that my dad really liked. He never liked any other guy but he liked him. I use to tell him that he was the only guy my dad has ever liked. Which was the truth. I don't know if he believed me or not but it was the truth and I tell the truth.

Yes, I think the most popular one is "I love you".

Yes, that would be one reason for saying such things. I always look at this as one of two motivations although I am sure there are others. The first is that she is showing you that you are a part of her world -- in her orbit. It is almost a rite of initiation to show to you that you have gotten into her close circle of friends, family, etc.

The other motivation is more a result of her being insecure and latching onto to those things that are close to her as a means of getting and keeping her hooks in you. That is not meant to be mean-spirited but when someone is insecure they may blow things out of proportion just to keep you close.
