The guide should eventually respawn as long as you have a house built. NPCs take a long time to appear, and require housing. One room is required for each NPC. You can check if a room is valid housing with the "Housing Query" option. Click on the house icon above your armor equip slots to swap to the Housing menu.

Good luck!
