Unmatching ends a conversation with a match. Bumble removes the chat and the match immediately, and you cannot undo it. Blocking removes someone from your match list and prevents future contact. It is private, she is not notified, and Bumble says that once you block someone you cannot unblock her. Use unmatching to end a chat and blocking to stop seeing someone, whether or not you ever matched.

Every cell comes from Bumble's own help pages on unmatching and blocking.

What unmatching does

Go to your Chats tab and open the chat. Tap the three dots at the top right, choose Unmatch, pick a reason if you like, and confirm.

The chat and the match are removed immediately. Bumble calls this permanent. The other person gets no separate notification, although she may see in her Chats that the conversation has ended.

Unmatching only works on someone you have matched with, because it ends a conversation that exists. It also takes the chat away from you, so save a phone number or a plan first.

What blocking does

Blocking removes someone from your match list and prevents future contact. There are two ways to do it.

If you are in a conversation, tap the three dots, then Block and Report. Bumble lets you choose a reason and skip the report if you prefer. If you have not matched, scroll to the bottom of her profile and tap Block, then tap Block again to confirm.

Blocking is private. She is not told. Once you have blocked someone, Bumble says it is not possible to unblock her, so do not use it as a way to cool off.

Bumble also says you can only block through the app. You cannot block people from your phone contacts, and you cannot hide your profile from a particular name or number.

Which one to use

For a chat that has run its course, unmatch. She has been polite, nothing is happening, and you want it gone. That is all unmatching is for.

For someone you would rather not see at all, block. The usual cases come from real life: an ex, a coworker, a friend's sister. You never matched, so unmatching is not available, and blocking at the bottom of her profile is the tool that fits.

For someone who has made you uncomfortable, do both. Bumble recommends the Report option for safety concerns, so its team can review what happened. Block and Report in the chat handles both at once.

Think before you press either

Both actions are permanent, and neither one tells her anything.

Men sometimes unmatch in a temper, as if it were a way of making a point. It is not, because she gets no separate alert. If you want her to know something, say it in a sentence first. If the chat is not worth a sentence, it is not worth an angry button either.

There is a practical reason to stay calm as well. a dating coach's experience is that dating apps take note of how men are received. In his view, men who say harsh things, get unmatched often, or get reported can end up shown to fewer women. A clean exit protects the account that is finding you dates.

When you are the one being left

If she unmatches you, Bumble says the conversation stays visible in your Chats along with the time of the last message. That is so you can still report her if her behavior was inappropriate. If it was not, leave it and move on.

Do not read an unmatch as a verdict on you. Women match, read a few lines, and change their minds for reasons that have nothing to do with the man. The best use of the next hour is to open the matches still waiting and write a good first message to the next woman you actually want to meet.
