No, you can't blame women for being who and what they are. Over a period of time, bit by bit, they give you clues as to who they are at the core. It can be a small act, or a simple statement that provides the clue. You were and are attuned to the signs of issues. It's all a matter of when we as men decide to act once we have the information. Sometimes you've made an investment, and bailing the moment something negative reveals itself means you take a loss. As men, we don't want to do that. So you hang in a little longer to get the pussy, or whatever it is that makes you feel that you're walking away with something to show for your time and effort, or whatever it is you've invested. These tricks are always playing us for something - it's just a matter of it being something small, or something major. But they're always playing an angle. We have to try to stay a step ahead. For the payoff, sometimes we have to go in and see what's there, then decide if we're going to move forward.
