when google messages gets deleted does that mean whoever still has it i wont be able to message?

No — deleting a message in Google Messages on your phone does not remove it from the other person’s phone, so they can usually still message you if they already have your number/thread. What gets deleted is your copy, not their ability to contact you.

What it means

• If you delete a chat , it’s typically gone from your device only.

• The other person may still have the conversation on their side.

• Deleting a message is generally permanent for your device, with no built-in recovery in Messages.

When they might not reach you

• If you blocked them, they may not be able to message you normally.
• If your number changed, service is off, or the app/network is having issues, messaging can fail for unrelated reasons.
• If the thread was removed only on your phone, that does not stop them from texting you.

Simple example

Think of it like tearing up your own copy of a note. The other person still has their copy, so they can still write back.

Bottom line

Deleting Google Messages on your device does not mean someone else loses the ability to message you. It mostly just clears the conversation from your phone.
