When the person who you cheated on find out—and believe he or she will find out. It is just a matter of time— it will feels like the world is collapsing on the head. It will be the darkest place that no one can imagine. It will bring the highest loneliness in the world to the person. It will push the person to the deepest depression (major depression episode). Depend on how much the person knows may push the person to PTST. The person will loose all the trust, confident, and much more. Now, tell me how does it sound like love to you? you claim you love your partner!!! Grown up and cut the $&@$
