To catch an unfaithful partner in the act or confirm suspicions 

Finding out a partner has cheated is never easy - but most people would rather know the truth than remain in the dark about their significant other’s infidelities 

The most common and obvious signs, he told us, are the ones such as spending longer hours at work, business trips, less sex, or defensiveness.

Noticing just one or two of the signs on the list may not mean a partner is necessarily guilty, as all relationships go through change 

Even if a partner isn't displaying any of the typical signs, your feelings may be picking up on something 

According to Martin, the signs are all the same, but catching someone is now as easy as picking up a phone or logging on to an iCloud account 

After seeing a significant other sneak away for a late night phone call or hide a text message, people are now “catching them themselves,” he said

If you do have an inkling that your significant other is cheating, looking for any one or four of the signs may part your mind at ease
