Spike, either through some miraculous gift or from his upbringing, has the most amazing capacity for love. He seeks out out even when it hurts him, and once he's found a source that he believes will bring him love in return he clings to it. Once he has a family or familial grouping of people, he will stay with them until he is somehow physically separated from them- the Fanged Four, the Scoobies, Angel's friends, the Asylum crew, - so, in the end, I think he will stay with his new family for as long as he can. Unfortunately, as long as the people he's around are mortal, the possibility that one day he'll once again be alone will always loom over him. There's also the possibility that he will one day be more monstrous in appearance like the Master, which will make it hard for him to stay around regular people. All of which brings up my second favourite aspect of Spike's character- his ability to adapt and survive. I heart my manpire vampire-man. *hugs him*

Thanks for reading! :D
