Why the thoughts are so intrusive
The brain's response to a significant attachment loss involves heightened vigilance toward cues related to that person — similar to how trauma produces intrusive thoughts related to the traumatic event. You're not failing at “just not thinking about them.” Your brain is doing exactly what it's built to do when a central relationship ends.
What makes it worse
Re-exposure through their social media or mutual friends' content re-triggers the pattern each time. Rumination — sitting with the same looping questions, usually about their behavior or what should have happened — is different from processing and tends to extend the intensity rather than resolve it.
What actually shifts it
Reducing re-exposure is the highest-leverage move. If you can eliminate the deliberate inputs (checking their profile, rereading messages), the involuntary thoughts tend to decrease faster.
When a thought arrives, the most effective approach is usually to notice it and let it pass rather than engaging with it — not trying to suppress it (which tends to increase frequency) and not following it into a rumination loop.
Building a life that has genuine content in it — things you care about, look forward to, are building toward — is slower but durable. The thoughts fill space. Fill the space.
Give the thoughts somewhere else to be.

Is it normal to dream about my ex?
Yes — very common, and not meaningful as a sign of what you should do. The brain processes unresolved things during sleep, and a significant relationship ending qualifies.
How long until the thoughts slow down?
Most people notice a real reduction around weeks 4–8 of genuine no contact. The key variable is whether you're continuing to re-expose through social media, which significantly slows the timeline.
