As for sms's (mobile messages) this has also been mentioned as a problem for some.
I was surprised at this idea myself, one reason to ask here. The whole article is about infidelity, and only part of it mentions technology. Where it comes in is among other things the interview person's views on monogamy: that monogay is in trouble and that it and infidelity should be viewed differently.
That there should be a different view on emotional and physical infidelity. On-line relationships are viewed as emotional infidelity.
Perel: "Infidelity, she says, is one of the great recurring themes of the human experience. "And we are not monogamous! We are not! "
"We need to start to understand infidelity in terms of the complexities of life today. We need to think in terms of the failed ambitions of love."
"We talk a little about the new, shadowy areas of human relations: the texts and email and iChats that may or may not qualify as cheating. Perel thinks that a flirty text message exchange can be as potent an infidelity as a fully fledged, physical affair. "So you don't touch? Sometimes this can be far more erotic than sex – because it all works in your imagination." Furthermore, this rapidly expanding field of infidelity is yet another reason for us to redefine monogamy. "Do we have to put monogamy on a spectrum? Do we need to think: what does monogamy mean to me? Does it mean no sex with other people? Does it mean not to look at other people? Does it mean not to fantasise about other people? Does it mean not to Facebook your exes? Not to text your friends? Where is the line going to be drawn? Monogamy today is no longer going to be assumed. It's going to have to be negotiated."
