How would you know if your husband is having an affair with another woman?

Well you didn't give much information here, I would wonder why you ask? "IF" you suspect then there must be doubt? Is it his past? Did he cheat on his girlfriend before you with you? They say if he cheated on her he will cheat on you? You didn't mention if your married to him or just dating for a short time. If your married to him- I would ask him point blank - Men Usually can't lie worth a hoot and you should be able to tell by looking him right in the eye. If your dating and don't know him very well, be on alert and just watch for a few weeks. If you still suspect then I would ask him the same way. Cheating is a sign of disrepect. I personally don't allow anyone to disrepect me and I sure don't want to be the last one to know. Good Luck and above all else Keep your dignity and don't allow yourself to settle for less than you deserve. Good Luck to you.

You could check for lipstick on his Weapon of Miss Destruction. haha Use your nose! You can smell out a cheater no matter how hard he scrubs up.

Man or a woman, when someone is having an affair there will be an unexplained change in their behavior, they may be more distant or even sometimes more sweet is they feel the guilt.. and of course the intimate relation may be greatly effected with it..
