Today, the message could be from work (who consider it fine to email at weekends and late at night), your bank confirming a new payment or a flirty text from a work colleague.In effect, the old boundaries have fallen away and anybody can come into your house – metaphorically – at any time and you’re going to be none the wiser if your partner is text cheating.That brings up a whole range of new dilemmas: In the happiest marriage, it is easy for technology to intrude and come between you and your partner.

I found out my fiancé had been receiving more than friendly texts from a woman that he previously worked with.

We had a horrific argument which ended in me leaving with our 9 month old baby – as my fiancé would not show me his mobile phone bill to prove he had not been participating in these texts.

We separated for one week and after discussions and an agreement that he would not contact this woman we decided to get back together.

One month later, I checked his phone and found he had saved the woman’s number under another name and had been phoning her constantly, and texting her at 2am when I went to bed and also throughout the day – even when he went to the shops to get nappies.

In the pre-internet age, with the phone in the hall way, a phone call after ten o’clock would be an emergency – like a teenager stranded at a party or the death of a family member.

Nowadays you can send or receive a text or an email at any time of the day or night.

If the phone rang, in the past, it was most probably a close friend or someone calling to arrange a social event (like a match in a golf tournament).

Any body in the house might answer and everybody had a rough idea of each other’s friends and engagements.

Perhaps you’d like to make the bedroom a smartphone/tablet-free area, so you can concentrate on each other – chatting over the day or having sex together.

What about meal times, when you’re watching the TV or going out together?

There are no right or wrong answers when it comes to smartphone etiquette but what gets our attention is what thrives.
