I was wondering the same thing. Is there a way to know if someone deletes your message from their inbox after they read it? I was friends on FB with a guy I used to work with. We've know each other for 10 years. We went on one date. I thought we had a great time catching up & then 2 days after the date he deleted me. It was such a weird thing. I had messaged him a few times before he deleted me that he never responded to & I wondered if he even read them.
