Unmatch
If you want to unmatch someone, open your chat with that person > tap the ellipses icon (Android) in the top right corner > tap on Unmatch.
Unmatching someone will remove them from your Matches list and you will disappear from their list too. This is a permanent action and it cannot be reversed
