Neither. Spike gets blown up in Sunnydale and Buffy goes on to live a normal life after Willow casts a spell to make all women able to stand up for themselves and be like Slayers. Buffy and malaikat do not get back together either. malaikat stays in LA fighting the evil there and Spike is ressurected and fights at malaikat side for the last season of Angel.
well if anda follow the comics which is a continuation of the series spike and buffy are lebih the end game it just going to take awhile because spike has been through alot since he got his soul and buffy has since the hellmouth was gone thanks to spike.
