The phone is not the intruder here
For couples in one place, the phone competes with the person in the room. At distance it is how the person arrives.
So blanket phone rules are the wrong instrument, and importing them causes real damage: the hour you protected is the hour you had together.
Separate talking to them from everything else
The distinction that matters is not phone or no phone. It is connection or avoidance, and they happen on the same device an inch apart.
A call is one thing. Scrolling while half on a call is another, and it is the version that leaves both of you feeling worse without either of you being able to say why.
- Time talking to them: the point, protect it.
- Time waiting for them to reply: where the scrolling lives, and worth blocking.
- Scrolling during a call: the thing that quietly does the damage.
The waiting is the hard part
Distance produces a lot of dead time pointed at a screen: waiting for a reply, watching for a green dot, checking whether they have been online.
That is where the hours go, and it is genuinely miserable. Blocking the feeds during those stretches while leaving your messages open is a much better shape than any general limit.
Agree the shape, not the amount
A fixed call every day beats a promise to talk more, because a promise is judged and a scheduled call happens.
Also agree what not replying means. Most distance arguments start with an unanswered message being read as something it was not, and one sentence about that in advance prevents a lot of it.
If you want to block something
Block the feeds, not the contact. Whichever tool you use, exclude your messages and calls, and set the window over the hours you spend waiting rather than the hours you spend talking.
Handing the key to somebody who is not your partner is worth considering here. Your partner already has enough roles in this arrangement without also being the one who says no.
Common questions
Should we set rules about response times?
A loose expectation helps and a strict rule does not. Something like a reply the same day, and neither of us reads a delay as a message.
Is it bad to be on the phone together in silence?
No, and a lot of couples find a silent open call while doing separate things is the closest available thing to being in the same room.
