There are many kinds (can't name them all off the top of my head)
1. Telling someone you'll keep it a secret and then tell anyway...

3. When you cheat on your husband/wife or someone you're in a relationship with
4. Using someone just to get some
Those are all I can think of (at the moment). But you can just pick whichever one you want.
Catastrophy, emergency, dilemma, disaster, change.
