Your brain is treating the breakup like an unsolved problem. That is why it keeps waking you up at 2 AM.

Here is the unfair part: your brain processes a breakup a lot like it processes an unsolved problem. When there is no clear ending, it keeps looping the tape at night, looking for one.
That is why you keep replaying the last conversation, the last text, the look on their face. It is not because you are weak. It is because your brain is trying to close a file that will not close.
Sleep hygiene advice alone usually does not work here, because the problem is not your pillow — it is the open loop. But there are things you can do at 2 AM that actually help.
If you are reading this in bed, try these in order:
Lying there forcing sleep makes it worse. Move to a chair or the floor. Your bed should stay a place your brain associates with sleep, not with 3 hours of replaying.
Open the Unsent Letter Vault or a notebook. Write the exact thought on loop. Getting it out of your head and onto a page slows the spin.
Your brain is pretending this replay will reveal something. It will not. Say it out loud: this is a loop, not a clue.
Fold laundry. Draw lines on paper. Do not scroll your phone — the blue light and the feed will keep you up longer.
When your eyelids drop, go back. If the loop restarts, get up again. You are not failing — you are retraining the association.

These are not magic, but they lower the volume over a few weeks:

If you have not slept properly for more than two weeks, or if the racing thoughts are scaring you, this is not something to push through alone. Poor sleep for weeks is a medical issue, not a willpower one. Talk to a doctor or a licensed clinician. There is nothing weak about getting real help for sleep — your brain needs it to heal anything else.
If the tape is playing right now, write it down in the Unsent Letter Vault. It is not a cure, but it can slow the spin enough to sleep.
