Using ellipses in the middle of a sentence is considered very rude.
Have you ever met someone who pauses in the middle of a sentence… just to fuck with you by injecting pointless suspense? Well, believe it or not… this is what ellipses communicate in written English. You’re building a lot of dramatic suspense and slowing down the pace at which people read your messages… and if you don’t pay it off… you seem like an asshole.
I don’t watch much reality television, but those shows like to inject massive pauses right before the judge reveals whether the chef made a good meal… just so they’ll gasp more and cry with relief and the audience will stay invested. But I hate it! It’s really annoying! And it’s how some people type.
