Mrs. Kersch: You know what they say about Derry. No one who dies here ever really dies.
Mrs. Kersch: I was always daddy's little girl. What about you? Are you still his little girl Beverly? ARE you?
Pennywise: Hello.
Richie Tozier: This meeting of the Losers Club has officially begun.
Answer: It's a bit involved, but the fact is that he was never that stable with the idea to begin with. He had forgotten all the horrors of his childhood (either due to the influence of Maturin the turtle [from the book] or Pennywise it makes little difference) and when it all started to come back to him, he panicked. And frankly, he had no way of knowing whether Pennywise could get him where he was or not. He didn't know enough to know one way or the other. But he knew that where Pennywise was concerned it would never be over simply. Pennywise would have tormented and tortured them like he did when they were kids, and when faced with that prospect he decided that ending it now, especially in his panicked state, was preferable to the idea of torture.
