There is nothing quite as shocking as discovering on a day that your spouse has been cheating on you for months or even years. Thousands of marriages and families are impacted in a destructive way by infidelity. Let us take a strong look at some of the warning signs that your spouse may be cheating on you.

They may be a paper trail left by gifts and romantic meetings between your spouse and a new lover.

#3. Family matters - Your husband or wife used to spend time with you and the children, but now seems to barely notice them or you. If you do not know what the cause of this unfamiliar behavior is, you should find out. It could be due to financial worries, stress or an illicit affair.

#4. Intimacy problems - If your partner is having an affair, it will have an impact upon your intimacy and sexual relationship. Your spouse has become cold, distant and uninterested in sex. Once again, you should determine whether the problem is due to physical illness, financial worries or an affair.

#5. Dressing up - Your partner has suddenly changed their appearance in a dramatic way. Hair, clothes, underwear and body. This may of course be due to some other reason than an affair. If your spouse does not really discuss these changes with you and do not seem to be doing it for you, they might be trying to look good for someone else.

#6. Suspicious stories - Your partner may start telling different stories on different days. They are seemingly confused about their day to day activities. This could be due to a difficulty in keeping track of their necessary whereabouts and alibis. They may also accidentally call you by a different name.

#7. Missing minutes - Your partner has started working late, but strangely their paycheck does not increase in relation to their overtime worked. If they were not working, then where was your partner and what were they doing? They frequently call you to say that something has happened and that they will be home late. Meetings and business lunches take much longer than normal. What secrets does these heinous hours hide?

#8. Driving to infidelity - Your spouse is using more gasoline for driving the car than normal. There seems to be much more mileage on the car's meter than your partner normally drives. Where are they driving to? Who are they meeting? If your husband or wife cannot explain this, watch out for a concealed affair.

#9. Nobody home - Sometimes, for no apparent reason, you cannot reach your husband or wife by phone. They either turn of their cellphone or do not answer it when you call. They do not satisfactorily explain this inability to reach them on their mobile or home telephone.

#10. Behavioral changes - Your spouse suddenly develops new tastes in food, music and lifestyle. She did not pick up these interests from you or your friends. Who is so strongly influencing her? From whom is she learning these new things?
