Being in a relationship isn’t always a bed of roses – far from it. Though the passion is always strong at the beginning of a relationship, routine, boredom, and petty fights can make it fade quickly.
Relationship problems, if not discussed and brought to light, can quickly grow, leading you to turn away from your partner, without realizing it yourself or ever talking about it directly.
At this point, cheating can provide an opportunity to escape, to take a breath of fresh air, though that might not be the excuse given. Instead people blame their own weakness, too much alcohol, or running into an old flame, to justify a bad decision, and all the lies and manipulation that come with it.
