The start of my Happiness 3

[Flight]

Why the affair? Because this person is emotionally weak. They have poor coping skills. Their world view stems from selfishness, immaturity and a sense of entitlement. Given certain stressors, lack of happiness, boredom, not enough sex, feeling misunderstood, etc. they feel they deserve to have those happy love feelings. Plenty of other people experience the same stress or lack of feeling their needs are being met and they don't cheat. They talk about it, try to work it out with their spouse, get help themselves, or leave the relationship. They don't cheat. A cheater cheats because they want to. They want those feelings and don't stop to consider anything above themselves and all the damage they will leave in their wake. That's really about it.
