What should I do?????

I kind of have the same problem when it comes to people that I'm "lusting after" so to speak and I don't have any thing in common with them. I start to make things up with out even realizing I'm doing it, they just come out. The "lies" that matter always come out. You know, the ones that you tell that are like the most important to a person. Try to be aware of yourself and what you are saying. If you say something that isn't true say something like haha just kidding and try to let it roll off your shoulders. Also, try being honest. Tell her she makes you so nervous that you find yourself lying to impress her or whatever. Maybe she'll be flattered.
