Should I send one final message for closure?

Not while the urge is at its highest. Draft it privately first, wait, and revisit it when your body is calmer.

What if I already opened the chat?

Close it now and move the words into the private pause flow. The goal is to add friction before the message becomes contact.

Need help right now

I want to text my ex.

Do not decide from the peak of the urge. Put the message somewhere private, wait 10 minutes, and choose again after your body has had time to settle.

Do this for the next 10 minutes

Put the phone face down for one minute.
Write the exact message in a private draft, not in their chat.
Wait 10 minutes before making any contact decision.
Send one safe-person message instead if the urge is still high.

Write it privately instead

This urge is information, not an instruction

Wanting to text can mean your attachment system is activated, you want relief, or your brain is looking for the familiar reward of contact. That does not mean contact is the safest next step.

Make the next step smaller

You do not need to solve the breakup tonight. The only job is to avoid sending from a state you may regret tomorrow.
