This is the trouble with cheating: there are no acceptable rules, or laws. It could be a smile, or dancing to a song that you considered to be indefinably 'ours'. It can feel like cheating to go to a restaurant that you used to go to with someone else. Keeping photographs of exes can infuriate, like retrospective cheating.

Boredom is not a thing. It's not a feeling or a condition. It is the absence of feelings, things and conditions.

My only piece of advice is that all of you consider every single text and Snapchat that you ever make as also being shared with your partner, because they all check your phones all the time - trust me on this one.
