He says there is a whole new way to cheat: electronic infidelity. "It involves all kinds of communication, interactions and hooking up that neither Shakespeare nor D.H. Lawrence could have ever dreamed up, and it's harder than ever to figure out whether your mate has broken your marital vows," he writes in Hitched magazine.
Infidelity: You may be surprised what makes men and women feel guilty after they cheat.
The 5 red flags of electronic infidelity, according to Dr. Scott Haltzman:
1. Private phone calls
If he quietly slips into another room and shuts the door just to answer his cell phone, be suspicious. Unless he is trying to hide something from you, his conversations should be public.
2. Erased history
Check her cell phone. If she frequently erases her incoming text messages and the call list on her phone, pay attention. Most of us are not that meticulous that we regularly erase lists of our calls. Doing so is a strong indication someone is sending her messages that she doesn't want you to read.
3. Private access
If he has just changed his password or e-mail address or changed something that denies you access you once had, it could be a sign he has a lover. By their very nature, electronic affairs rely on technology, and e-mail is at the top of the list. When married couples are open and honest with one another, they don't hide their e-mail accounts from each other.
4. Powering down
You walked into the room unexpectedly. Did she quickly turn off the computer? Internet chat rooms are an effective and common way to establish intimacy. Anything she wants to chat about online is something she should share with you and not hide from you.
5. Late night log-ons
If he stays up long past your bedtime working on the computer, do check the computer's "history" the next morning. If it's been erased, be suspicious. Electronic affairs don't always include face-to-face meetings; instead, e-cheaters meet online or visit pornographic sites that offer live chat.
