If your relationship came to a rather serious level, it is likely that women need to "reconquer the territory." It all starts from afar - it first begin to irritate your friends, then she opted for any one person, usually a man's best friend. And start a massive attack - she condemns his behavior, habits and lifestyle, laments the fact that communication with the person spoils man, etc. The calculation is simple - one gradually disappears from your life, and the object of criticism becomes the man himself. Cope with women's manipulation is simple - let her know that one appreciates her personality and appearance, it certainly flatter any woman's self-esteem. A man will be able to communicate with one another.
Women like to ask leading questions about their appearance, provoking men - never supported her argument that it's time to throw a bit of weight, go on a diet, his hairstyle, etc. On her part, such agreement will cause an uproar - hence, in its current state, it is not good enough and hairstyle she does not go, and generally where you could see the extra weight. Just do a surprised face and say that it is good just the way it is.
After intimacy woman likes to talk - do not show your lack of interest, but simply often tell her that she is wanted and loved. Not warm her interest, answering questions about how you liked best - woman necessarily uses your candor to get into a fuss and offense.
