Say you've been cheating on your partner and have lied about it, mostly to uphold the idea that you're a good person and you also just can't admit to it. They don't believe you however. You're not sure if you want to save the relationship as you're fed up with arguing and being snooped on. However it would be easier to stay together in many ways. Your partner then says they will give you another chance as long as you swear on your child's life that you haven't slept with anyone else (you definitely have). You're not religious or superstitious at all and you don't really believe in that stuff. Would you do it?
