I'm looking for fics where Spikes gives up Buffy and trying to prove his love and worth for her and the Scoobies and actually moves on and doesn't return to Buffy because it was expected of him

Haunted by Kantayra

Seven years ago, Spike fled Sunnydale and his abusive relationship with Buffy. Now, he and still-best-friend Dawn are working together in their own demon hunting agency. However, when they're called out to investigate a chain of supernatural murders at Cascade Mountain Lodge, they discover that Buffy's on the case as well. Will they be able to solve the mystery before they become the next casualties? And what does the solution have to do with the events of seven years ago?


Cast Me Not Away by Enigmaticblue

A long series exploring the ramifications of love, loss, and belonging. Spike leaves after "Dead Things," wanting nothing more than to get Buffy out of his head. Wesley's still an independent contractor after the events of "Loyalty." And Buffy's still living in the land of denial.

Spike heads back in this because of fears about complications of the empowerment spell effecting his current slayer girlfriend.
