I have a question why is it that men say one thing and do another?
It's called manipulation and is not just inherent to men. Many people do it, men and women alike. It only takes someone to manipulate me once for me to end my association with them. I'd suggest you do the same if it happens to you.
With all due respect, I think you've been hanging out with the wrong type of men.
That's a rather sexist post. Perhaps you would do well to ask yourself why you attract those types of people to you.
