4 dots in a text

What does 4 dots in a text mean? It means "we'll see, end of discussion for now."

Unlike the three-dot disappearing act seen while texting, where the implication is that the conversation is still going, the four dots in a text message is similar to NRN and EOD, which indicates "no reply needed" and it's the "end of discussion." The first three dots are an ellipsis () and the fourth dot is a full stop period (.). 

A similar I take your question response is when someone signs off with xo.
