What does it mean if you accuse an sw person of possibly being a catfish and then they block you?

The worst catfish story I've ever heard this guy worked for a security company that I was a supervisor for and he kept always wanting to get an advance on his paycheck and it fill out the paperwork so we give it to him come to find out he was sending her close to 3,000 a month and he never so much as talk to her on the phone. We finally as his friends said listen if she truly loves you or anything you need something real you have sent her more than enough money that she could have bought a car and driven here. I left the company soon after that so I don't know what the eventual outcome was but we kept trying to convince him that she was a scam
