I lied about a vasectomy as a prank and it ruined my life.
Why did you lie about getting a vasectomy?
Just to torture my ex.
You shouldn't lie about a vasectomy to anyone. You need to consider the consequences of pulling such a prank.
I didn't see any cons on lying about a vasectomy. Now that she knows the truth, I can't get my ex back after all the confusion.
This is why it's important to think about what may happen before you pull a prank. Lying about getting a vasectomy is not a harmless prank, and is a lie about a serious medical procedure. It's not surprising that your girlfriend wanted to break up with you after finding out what you did.
