In Season 7 Episode 22, why do 你 think when Buffy 说 "I 爱情 you" Spike replied "No 你 don't, but thanks for saying it"?

I think he 说 that because he wanted her to live her life because he knows that now she can because she's not the only slayer!

Because he knew she didn't 爱情 him, otherwise she would have 说 it sooner. She just 说 it to let him die happy 或者 to give him a sense of accomplishment 或者 warmth 或者 to let him no he wasn't alone. Because even though she didn't 爱情 him, they were still very close.

cuz he knows buffy to well to no that she could never 爱情 him she says it to let him that she does 爱情 him but not in the way he would like

I think Buffy 说 it because she felt guilty. She was a douche to him a lot and used him and flat out 说 so, and he still died to save the world, which included Buffy. I think she loved him, but she wasn't in 爱情 with him and felt like she had to say it.

He knew she didn't 爱情 her, but that it was something between them. It was also a last 分钟 line

He didn't believe her. I can't think of any other reason for him to say it was a lie. He just thought that she was trying to comfort him and give him what he wanted, since he was sacrificing himself. She probably did mean it though, and had only just realised too.

In my mind, I think Spike had other reasons for telling Buffy that she didn't really mean it when she 说 she loved him, but thanked her anyway for saying it.
