When men act up by being degrading, dismissive, condescending, shut off, or sullen, that can often dumbfound you as a woman and get you off balance. At that point, you can feel and look like a deer in the headlights, which makes you even more vulnerable to such a man's next volley of vitriol.
One reason some people are long-winded is because they're trying to impress their conversational counterpart with how smart they are, often because they don't actually feel that way underneath. If this is the case for you, realize that continuing to talk will only cause the other person to be less impressed.
Denial is not always a bad thing. Without it, you couldn't function. For instance, if you were hyperaware and hypervigilant regarding all the dangers in the world - from driving your car to crossing the street to eating food that might have contaminants in it to taking medications that have many side effects, etc. - you would become frozen.
