The end of a relationship can be devastating - especially when infidelity is involved.

But what if you could spot the tell-tale signs of a cheat and call them out on it before it was too late? Reddit users whose partners have cheated on them have shared the signs to look out for - and they're surprisingly subtle.

Users cited common signs of infidelity as the guilty party becoming aggressive about the idea of cheating - and even accusing their partner of being the unfaithful one.

Other signs to look out for in a significant other include showering at odd times of the day, taking phone calls late at night, and being vague about their whereabouts.

One Reddit user said clues are often right there in your partner's behaviour - like rushing home to take a shower even when they haven't been to the gym.

Another woman even revealed that she received a wedding invitation from her partner's fiancée, confirming that she was in fact the 'other woman' in his life.

Other signals include lying about where they are and speaking on the phone late at night

Men and women who have been wronged by their partner said their body language had also been a big giveaway.

They also described their partner talking about another woman regularly, or having unsaved numbers in their phone as clues.
