Worst April fool's joke ever?

So someone posted .....let's call it a cry for help on popular website Nairaland, she just played the worst prank on her boyfriend and it has backfired. her words below.

"he is abroad ,this morning to play on him I sent him a message on watsapp that I slept with another guy last month and I just discovered I'm pregnant now the guy wants to marry me...he got annoyed said he was disappointed and betrayed... before I could say April fool he has blocked me and he won't pick my calls ... and we did have an agreement not to play pranks on each other because of the distance ....what do I do now ? I'm hurt ."

 Chile first of all how old are you? do you not have friends? its bad enough when you are in a distant relationship, where do you suddenly wake up and decide i will just destroy my relationship.

Nigerian men are possessive , no one is laughing if you are joking about sleeping around, poor misguided child.
