In the most cloudless relations there are things which cannot be done at all. In particular, there is the whole list of subjects which you should not mention if you do not want to offend the man.
The most improper subjects for a talk
First of all, it is impossible to criticize the man's mother. In your disputes with the mother-in-law the man will always be not on your party. So you should not "be set up" independently.
If suddenly in your biography there was unfaithfulness to the former partners, you should not remember it at the present man. He will suspect you, to feel fear and a stress, and it can seriously spoil even the strongest relations.
Do not expatiate on the former partners in sex. If there is a question, answer and do not return to this subject.
Do not criticize appearance. Men extremely painfully treat criticism of this sort. The bad hairstyle, a baggy sweater, too bright socks – all this does not cost his offense. If you can correct something, silently and imperceptibly make it. Never doubt its opportunities. To it it is very important that you supported him even in the strangest undertakings. Nothing will wound the man as doubts of the companion of life. And it is unimportant that he is going to submit Everest or to fly to Mars. Most likely, this momentary decision which he will soon refuse and will forget. And here it is so simple to forget your doubts and criticism it will not turn out. You do not stir dirty linen of the friends in a talk with it, besides you should not speak about their unfaithfulness, especially in a positive key. It can wake in the man fear and doubts.
Do not threaten, do not reproach, do not remember others...
Never you threaten to leave it. Control yourself during the quarrels, if you regularly threaten with the fact that you will leave it and will find somebody better, the man can believe that it is only temporary option. Do not reproach its with the fact that you earn more (if it, of course, so). It strongly touches the man and can be reflected in his self-assessment, so, and your relations.
Perhaps, this list is relevant not for all men, however you should not check it by practical consideration.
You do not lead the conversation that you wish other men. In the presence of the man do not hint and do not think that you would like to appear in a bed with another. Men quite well feel similar thoughts and intentions. So, having even made of a situation light, to it you will seriously spoil mood. And within the next hours or even days you should convince the man of own irresistibility.
