No. Facebook says that blocking someone in Dating does not block them on Facebook or on Messenger. The rule runs the other way, though. Anyone you have already blocked on Facebook is blocked in Dating automatically. So a block on your main account covers both places at once.

Two separate blocks

Dating lives inside the Facebook app, but it keeps its own list of blocked people. A block you place in Dating does not follow that person out to your main Facebook account, and it does not reach Messenger.

Your main account works differently. When you block someone on Facebook itself, Facebook carries that block into Dating for you. So one kind of block covers both places, and the other covers only one.

If you want the Dating block, the steps are short. Tap Menu, then Dating, then Matches, tap the person's picture, tap Options in the top right, tap the Block option with their name on it, and confirm.

Why the difference matters

Facebook is not an anonymous app. Your main account usually carries your real name, your friends and years of photos. A woman you blocked in Dating may still be able to find that account, and she may still be able to write to you on Messenger.

For most blocks, that never comes up. You blocked a spam account or a chat that went nowhere, and nobody is going to look for you. But when the reason for the block was serious, a Dating block on its own leaves two doors open.

Shared friends add a third. If the two of you know some of the same people, she may still see your name under their posts and photos in the ordinary way. A Dating block does nothing about that either.

When a Dating block is enough

  • A scam or fake account. Nobody real is behind it, so there is nothing to follow you anywhere else.
  • A chat that turned awkward. You want it out of sight, and that is all.
  • Someone pleasant who keeps writing. You said you were not interested and she did not take the hint. A Dating block normally settles it.

When to block in both places

  • Threats or harassment. Anyone who has made you uneasy about your safety.
  • Someone who has already crossed over. She found you on Facebook or Messenger after you went quiet in Dating.
  • A clean break. You dated her, it ended, and you need it to stay ended.

For those, take screenshots of anything threatening before you do anything else. Report the account from the Options menu in Dating, so Facebook can look at it.

Then block her on Facebook itself and check Messenger as well. Facebook's help pages walk through both. Once she is blocked on your main account, she is blocked in Dating too.

A clean break helps you more than it hurts her

When a man blocks a woman after a bad ending, he usually worries that it looks petty. It rarely matters to her as much as he fears. What it really does is take away his own temptation to check her page, reread old chats and send one more message at midnight.

The standard advice after a breakup is to put barriers between yourself and contacting her, because you will not always feel as sure as you do today. Leaving one door open is how a finished thing drags on for months. If you are done, be done in every place she could reach you, and every place you could reach her.

If she blocked you

The same rule works in reverse. A woman who blocks you in Dating has not necessarily blocked you on Facebook.

That is not an opening. If she ended contact in Dating, writing to her on Facebook or Messenger is the quickest way to turn a quiet ending into a report. She gave her answer in the only place the two of you were talking. Take it, and put your attention on the conversations that are still going.

Keep it in proportion, too. Women end conversations on dating apps all the time, often for reasons that have nothing to do with you. She met someone. Her week got away from her. She deleted the app. One ended chat is an ordinary part of using any app, and the men who do well treat it that way.

Keep the good conversations somewhere sturdier

Anything that lives only inside Dating is fragile. Blocks, deleted apps and changed minds all make chats disappear.

So when a conversation with a woman is going well, move it along. Ask for her number, suggest a specific evening, and let the app drop out of the picture. Once you have a phone number and a plan, no block on either side stands between you and the date.
