No need to say anything to him because it will just be yet another back and forth. Just don’t reply or block.

Half of the things he says are exaggerations or lies anyways. You don’t really know if it’s truly time of need or yet another lie. He went to ER for dizziness. I hope he won’t send you his medical bill to cover. Last time you broke up he claimed some other emergency condition. In reality he just did too much cocaine (possibly his current dizziness and heart fluttering it what are also drug or withdrawal induced). I’d not trust anything he says. You also do not know if you are the only person he’s contacting.

This is not the case of needing to be there but someone. He’s manipulative and dishonest. No need to feel obligated to be “there”
