they become surprised that you took them seriously? Do they like just being a piece of meat?

I think you have a good question there but just not quite sure what you are looking for. Some gals just like to flirt so they are not being serious their self and I don't think any gal want to be just a piece of meat.

Caveman psychology is "the woman wants to be wanted" and the man "wants the woman to want it". Is that what you are looking for?

Can you add details so we know exactly what question you are asking?

HIS DETAILS:

"I met this woman thru work and we started sharing details of our lives, started flirting, talked about romantic things/details/meetings. Just heart to heart stuff and after all this, she decides that she just wants to be friends. I gave her several opportunities early on to draw the line somewhere and she never did until she knew that I was falling for her.
That's the gist (sp?) of things. Any insight?"

My response:

You know, there are just women out there who do stuff like this. They like to play games and see who they can attract. I am sure it boosted he self-image to play the game. On the other hand, there are women out there who actually are looking for the real deal. I am not sure how to tell you how to recognize the difference...but I will tell you not to let this woman spoil it for you. Continue to put yourself on the line (even if it hurts a bit here and there) because you will eventually meet the right person for you.

I hope this helps!
