the only real answer here is this one from tommo


I think people have a natural curiosity about other people. Whatever you do, try not to take offence to it. It isn't usually what it seems. I had it a while ago with somebody and I mentioned it and after a bit of talking it came down to the fact that I also look at other people, but I wasn't analysing what I do... just what I noticed her doing.. It is just a curiosity. After all, just because you are with somebody doesn't mean that she/he is supposed to only look at you... Take no notice... AND BY NO MEANS SHOULD YOU START PLAYING HER... because you could end up messing with a good thing you have :-)
