Hopefully there no update because they both decided to put down their damn phones, ipads, and whatever other technology, and work on their relationship. Technology makes infidelity that much easier. It's apparent that neither fully trusts or is totally committed to the other. If they can get back to basics, it may work. The trust will take a long time.
Someone that does not have the ability to trust is unlikely to be very trustworthy themselves.
They really need to look at each other and decide if that person is what they truly want. I know all this is basic cracker jack advise but there is no secret formula. There is either love, devotion, and trust or there isn't.
