What a block communicates
A block is a decision to stop spending energy on deciding. It is not usually a statement that every future word from you is worthless. It is a statement that the person no longer wants to be the filter.
Understanding that changes what a reasonable next step looks like. Anything that puts them back in the position of filtering unannounced contact ignores the point of the block.
What not to do, in order of how badly it goes
These are the routes people take when they are hurting. Each one converts a private disagreement into a safety concern.
- Messaging from a new or borrowed number.
- Creating new accounts to reach them on another platform.
- Contacting their friends, family or employer to pass on a message.
- Showing up anywhere you know they will be.
The one route that can be fair
A request that identifies itself before it delivers anything is different in kind. The person sees that someone is asking, sees what it cost, and chooses. They can decline, block the sender permanently, or opt out of receiving anything at all. Nothing is revealed unless they choose to open it.
That is the only version of contact after a block that leaves the boundary intact, because the boundary is enforced by them rather than trusted to you.
If they say no
Then it is finished, and you know it is finished. That is worth something. Most of the pain of being blocked is uncertainty about whether one honest attempt would have changed anything. Making the attempt once, properly, ends the loop.
