Make sure that your lover is a reliable person, before you have a serious romance. Try to understand what he wants from you actually. Sometimes there are despicable people who, over time, for example, can start to extort money for his silence. So do not tell immediately where you live and work, and who your husband is.
Hide any contact lover: the numbers in the phone book, addresses and web pages, etc. If you can't remember them, then improvise: use of women's names, posts, etc.
Agree with lover, what days and hours it can call or write. For this you need to thoroughly know the work schedule of her husband, the schedule of meetings, conferences, trips that he ever came home in a piquant moment.
Invent a situation that will allow you to call your lover even at a time when husband is home: to make a call, you can, for example, to go upstairs (under the pretext to smoke or throw garbage). And to meet, tell your husband that going to the store, the clinic or any other non-suspected cases.
Do not meet with a lover near your home and in public places. Not only that, you can randomly encounter with her husband, and passers-by can suspicious to the woman who appears with one man, then another, and communicate about it to your spouse.
Choose a suitable place for meetings. It may be the cafes, cinemas and shops in which to your spouse or friends just will not drop. It is desirable that they were located as far away from home, possibly in another district.
Keep your adventures a secret. Secret need to know only two people: you and the lover. To talk about it, not even best friends. You can never know in advance whether you can trust the person, whether there will be it a secret or not.
