If I Was So Sure God Was Telling Me It Was Going to Happen, Why Didn't It?

You were so sure it was going to happen.  Little things kept confirming it and you just felt it in your bones.  All signs pointed to it being right.  When you prayed about it you felt peace, and even though you asked God to make it clear if the thought wasn’t from Him, it persisted.  But now, it didn’t happen and you’re disappointed.  And confused.  If it’s not going to happen…why did I feel like God was telling me it was?
