A couple of ways women show attraction:
Well from my experience women who are attracted to me are at best accepting of my pursuit of them, In the same way that a deer will sometimes let you pet it, by not running away. But even in this there is a sort of tense discomfort, as if they have let Shrek on to the Parade grounds and at any moment he is going to unleash his vengeance on the Castle.
At worst they play games and are flighty, like a leprechaun luring me into their Labyrinth of mind games. They like this and that and this and that, and if you don't like their list as much as they do, a magical trap door opens and suddenly I'm outside again, no longer as attractive as before.
Whenever its real attraction, and I strongly feel it from her, its strangely forbidden. I really like you, but my husband blah blah blah(I sort of zone out after hearing husband). I really like you but, I'm not 18 yet. I really like you but, I have 5 warrants for shoplifting and I'm a pot dealer. I really like you but I hate Men and Sex and I have massive carts of baggage and I will probably cheat on you.
