i am posting this doesn't mean to support the people to have an affair, but if you are having or gonna have.....please read the expert's as below:
Most everyone believes when they get married that it will be forever. However, the reality in today's world is that many marriages fail and result in divorce. Other married couples may fall out of love and grow to dislike one another more than they care to admit. But for a variety of reasons (kids, money, religious beliefs etc...), they remain husband and wife in theory primarily.
Never bring your lover to your home.
Never go to your lover's home (unless they are completely single and free from the ties of marriage and/or a serious relationship.) If they get caught by their significant other, chances are your spouse will also find out.
Never call your new companion from your home phone and/or your cell phone (if your spouse has access to your phone record.)
Never give your new friend your home phone number.
Keep a low profile when you are out with your lover. You would be surprised how many people know you and/or your spouse, who unbeknownst to you may see you lavishing inappropriate attention on your new companion in public.
Do your best to meet with your lover out of town - somewhere far enough away from home that you do not know people and people do not know you.
Try to set up a regular schedule of "dates" with your lover. If your spouse expects you to be out of town for business overnight every Wednesday, he/she will not suspect anything when you maintain this schedule and include your new friend in your overnight stays.
Do not become too confident in your ability to deceive your spouse. If you become too sure of yourself, you will get sloppy and you may get caught.
Do not tell everyone you know about your illicit trysts. You should trust very few, if any, friends with your secret.
Do not make promises you cannot keep. Nothing will prompt your lover to reveal your affair to your spouse quicker than your failure to fulfill some insincere commitment to end your marriage for him or her.
