I'll probably start with the most obvious to least obvious!

So number one is communication!

This one is probably the MOST important in a relationship!

Communication can come in many ways!

Talking and having conversations, checking in on each other, remembering boundaries, or the the honky dory you do when no one's around (Lenny face)

Whatever it is it is very important in order to keep a relationship strong!

If not many things could happen!
We will just put it in a P.O.V to make it easier!

when no communication is happening it could make that person feel very mixed signals! Now I get it you may be busy or want to hang out with your friends and that's valid! People need personal lives! But if you make it where you don't talk to the person for months they may feel these things-

1. Lonley, this one is something nobody should feel in a relationship because the purpose is for each other to make each other, not Lonley. If your partner feels this it could be in indicator you need to change things

2 hurt, if your loved one is feeling this, then you are in the red zone my friend! I'm pretty sure you don't want to hurt your partner (hopefully) but not communicating for a long time can lead for them to over think, feel like they did something wrong, and make them regret things they've said before!

3 unloved, this one is very bad! Like break up risk bad! If your partner feels this it could cause you to break up! (All of them can cause it but this one is big) when feeling unloved while in a relationship can really be a hurtful thing for your partner.

So just keep in mind these feelings when your are taking a break from them for abit

How long should you go without communication?

The real awnser is never, but if you need to go due to work then the most you should go without saying anything depends on the person. First tell them you'll be gone but let them know you'll be back BUT HANG ON CAUSE THAT DOESN'T MEAN YOU CAN LEAVE THEM FOR MONTHS!

The most you should go without saying a word should be a week if you want to keep things safe!

This will transition to the last part of the puzzle for now

What to do when you can't communicate?

You should try to find ways to talk to them when you have at least some time to talk, because if you keep choosing to pick other things to do then saying a simple hi or check to see if they are okay then it can lead to break up real fast!

(And in my opinion it's really rude to just ignore them especially if they try everyday to talk to you)

I'll update more soon! (In fact I might make another chapter after this one)

If you have any questions let me know! ^^

Bye! :3
