I met my girlfriend by catfishing someone else
Why would you catfish someone?
It was fun to catfish them.
Catfishing someone is very disrespectful and you shouldn't do it. Lying is bad in general, but pretending to be someone who you aren't is even worse.
I did nothing wrong. It wasn't my fault that she fell for it.
Well by lying you did do something wrong. It's wrong to pretend that you are someone else just to get a date.
