@Dora Buffy had her part to play in Spuffy. She was in a bad place emotionally which led her to make bad choices and then CHOOSE to continue doing so. She didn't "accidentally" have sex with Spike on multiple occasions, she chose to seek him out for sex because it made her feel better temporarily. It is NOT a case of big bad Spike and poor little Buffy. Buffy had agency. Spuffy was a MUTUALLY unhealthy relationship for BOTH participants.
You've come back wrong ,what sort of demon are you, Spikes words , he knew she was not the normal Buffy that she was not the Buffy he professed to love , he showed his love by mocking her in the morning after smashed,
Buffy used Spike as self harming because she was mentally ill , but it was Spike who still stalked her not seeking to help her , help with Dawn but just use her for sex , Balcony, outside her home, at her work for instance , she does not understand ? as she asked Why do I keep letting him in ?
Buffy is shown trying to fight her feeling's when she shows at Spikes door in Dead things and thanks the heavens when she hears the scream, Buffy life at this point was patrolling , fighting , money problems, working a job she disliked , a bitch of a sister, her depression and Spikes sexaul abuse no wonder a prison cell would seem to be a better choice
Buffy apologised after Riley's speech, Buffy apologised to Spike even calling his human bodies name of William she realised she had just been using him for self harming , she said sorry and when he said he did not mind, she told him it was killing her.....his answer was to try to rape her
At this point Spike is a demon so no blame can be put there , despite the writers not knowing to make him good or bad...
What I hate is they showed Buffy having sex with a animal..... a thing that has taken over a dead man's body
Why do I hate season 6 so to feed Noxon's ego , to feed Spuffy , they had to make SMG do thing she did not want to do things Sarah said buffy would not do , Noxon said at the end of S6 they knew Sarah would not sign on after her contract run out , recently Noxon has said they went to far Perhaps it was right not to carry on as S7 turned into the Spike show and the mostly criticized season
Without firefly , without S6 would we have got more Buffy ? and if so would it have been as good as the first 5 seasons , the workload on Sarah was enormous , she couldn't carry on have giving so much of her life to a tv show but I am sure there was ways if , Whedon had really wanted to lesson that load
