The relationship is over or "The offer ends soon!" The left-pointing arrow with the word "END" may also ask you to go to the end of a song, a movie, etc. It can also express an emotional state, such as "I'm at the end of my tether!"
The END arrow emoji was introduced in 2010 and released as part of the Unicode 11.0 standard. This emoji can be found under the symbols
