One of the signs of infidelity is that his stories seem suspicious. Does he tell elaborate tales about why he was late getting home from work? Do these excuses not quite make sense? If so, consider what this might mean.

And although it's always nice to get gifts from your husband, if he's been buying you a lot of nice things lately and it seems out of character, watch out. He may be buying you all these things because he's guilty of sleeping around.

Sometimes, though, husbands might pick fights at the drop of a hat. The reasons for this are twofold: it may be a coping mechanism, a way of dealing with his guilt over cheating on you, but it also is a good excuse to storm out and rendezvous with his secret lover.

Another one of the signs of infidelity is drastic changes in appearance. Is your man suddenly taking a renewed interest in his appearance? For example, is he ironing his shirts or wearing cologne, even though he normally doesn't? This could be another clue that he's seeing somebody on the side.

If either your level of physical or emotional intimacy seems to have decreased, this yet another sign of an affair. If you don't spend as much quality time together as you used to, maybe it's because he's spending more quality time with his mistress.

Remember, this is not a comprehensive guide. The important thing to remember is to trust your own inner feelings. Are you suspicious of your husband because he's been engaging in behavior indicative of an affair or are you so insecure that you see the signs in the most innocuous things?

If he is, in fact, cheating, remember that healing after an affair is possible. For most couples recovery is possible and the marriage can become better than it ever was. Take a long look at what you've put into your relationship before you decide to leave. And regardless of the outcome for your relationship, make sure to thoroughly address your feelings about the betrayal or the hurt will resurface in the future and cause more problems.
