When he announced a similar transgression on Tuesday in the middle of his New York City mayoral bid, many came to question Weiner’s impulse control.

Whether or not ‘sexting’ is cheating is a really tricky one to call. Change in sleep patterns – Chat rooms and online meeting places heat up late at night, so the cheating partner tends to stay up later and later to be part of the action.

For a partner once willing to communicate about contentious matters, this could be a smokescreen for an online affair. Loss of interest in sex – Some online affairs evolve into sexting, phone sex, or an actual rendezvous, but cybersex alone often includes mutual masturbation from the confines of each person’s computer room.

If sexual relations continue in the relationship at all, the cheating partner may be less enthusiastic, energetic, and responsive to you and your lovemaking. Declining investment in your relationship – Those engaged in online affairs no longer want to participate in the marital relationship.

They shun those familiar rituals like talking over the dishes after dinner or renting a video on Saturday night.

Of course, it depends on so many things – the relationship you are in, how long you have been together, how open your relationship is, how often your partner was ‘sexting’ behind your back, and to whom, and so on. Often, the partner suddenly begins coming to bed in the early-morning hours, may leap out of bed earlier and bolt to his smartphone for a pre-work text or email. A demand for privacy – If someone begins cheating on their spouse, whether online or in real life, they will often go to great lengths to hide the truth from their wife or husband.

But if it did happen to you, how on earth would you deal with it? Because these are virtual relationships, it is hard to tell if you dealing with an online affair or your very own sexting scandal. With an online affair, this attempt usually leads to the search for greater privacy and secrecy surrounding their mobile or computer usage.

Note: there are also many excellent for-pay support and therapy groups online that are not listed here. It is worth emphasizing that support forums are only as helpful as the people who are on them.

This means that the quality and extent of support and guidance can vary from group to group and time to time.

I encourage anyone who has information about additional online and telephone support forums to contact me so that I can include them here.

Remember, addiction and despair breed in isolation, while recovery and hope thrive in connection.

Family, friends, therapists and others may all have something to offer, but each have their own limitations. For sexual issues, 12-step groups can be very valuable.

(I often encourage people hesitant to attend a 12-step group to read my article titled "12 Step Groups: Twelve Objections and Twelve Responses." ) However, there are lots of reasons why a person may not be willing or able to attend a support group in person.

They don’t get as excited about taking vacations together and they avoid talk about long-range plans in the family or relationship.
