Buffy had told Spike right from the start of his obsession that she was not interested, he even chained her up to make her say she had feelings for him. I don't think Buffy gave him any indication ever that she loved him, she apologised for using him because to a certain point Spike was Buffy's self harming, but the main culprit was Spike he knew she had come back wrong, depressed, different Buffy went to him as a confident but instead of helping Buffy he took advantage of her mental illness and abused her.In gone he arrived in the morning and sexually assaulted Buffy despite her saying no, did she not get cut her hair off because Spike said he liked it , later she went to Spike but she was acting completely out of Character once she was invisible,making out the social worker was nuts , stealing the car, the hat and Spike said you are only here because your not here did'nt stop him having sex with invisible Buffy though did it.I think the only good point of Gone was the fact Buffy told Willow that she no longer wanted to die.Spike pestering Buffy for sex kept Buffy depression going longer that's why Riley's talk made Buffy realise if she was to get better she had to break it off with Spike she had to stop self harming, it started the proceed of getting better.Turning Buffy was never a issue, not only did Spike not know how she would turnout ( his mother ) Spike was obsessed with the Slayer not Buffy but the Slayer . No if Spike wanted to impress Buffy he could have gone and got his soul at anytime, then they could well have been a couple, but if you believe that Spike went and got his soul after the AR then the only reason he did it was it was the only chance he would have to get back in Buffy pants, what better line chat up line, than "I did it for you" making Buffy feel guilty for using him to get her to accept him back . As for Fans having sympathy for Spike read what JM has said he said he acted that so that even when Spike was at his worst he made fans synthetic to Spike.... he needed not to be staked he needed the money
