Why do people cheat? If you aren't satisfied in a relationship, why not say so or end the relationship? If you're looking for a "thrill," why not thrill yourself with something that doesn't put someone else's emotional health at so much risk?
People cheat because (1) the grass looks greener in the other pasture; (2) they get the "hots" for someone else; (3) they are self-centered selfish people who want what they want when they want it; (4) they become emotionally connected with another individual; and (5) they're horny and sex with a new partner is more exciting. I'm just guessing at those, but I'm sure some other people will have more reasons why people cheat.
