I avoided this discussion for so long....
Just for the record, I don't only think it wasn't love because of Bangle either.
It wasn't love because she said she loved him yet didn't mean it...
It wasn't love because they treated each other so badly...
It wasn't love because ultimately they were just convenient for each other...
It wasn't love because it wasn't the real Buffy... she changed when she came back from the dead...
It wasn't love...
Does Spike rejecting the words make them not true? I don't think so, I think it says more about Spike's state of mind than Buffy's. I maintain that Buffy is not the kind of character who would say 'meaningless nothings' just to make someone feel better, even in the face of death. OK, so Buffy didn't argue with him - well, can you blame her; the hellmouth was caving in and she knows what it means to give your life for a greater purpose (as in The Gift), she respects that. I think her not arguing shows that she respected Spike and what he was doing not that she didn't love him. Earlier in the season in 'Him' the message came through loud and clear that 'no guy was worth dying for' so it is hardly surprising she doesn't stick around to be crushed to death beside the man she loves - god, wouldn't that be melodramatic (and it 'ain't my idea of love...)
Also, you can't judge a statement made at the end of season seven (as in "I Love You") just with season six evidence - that's not fair and of course it would be difficult to prove the case of love!
When did they treat each other badly? Season six, yes but in season seven all I saw was progressive development in their relationship that saw Buffy forgive, help, believe in and trust in Spike. Their was friendship, there was affection, there was mutual trust and respect. There was also the odd angry word but those were few and far between and all for the purpose of getting Spike to be a better man, pushing him along on his journey to championhood, when he thinks he's nothing but a piece of crap.
When did Buffy treat him like a 'conveinience'? Season six, yes, but in season seven she relied on him - Giles sees it, Buffy says it, and I don't think its out of conveinience at all.

Splainey???
For me, love is about actions. Like the old saying says - 'actions speak louder than words'. It is possible say words and then not back them up with actions or you can show love through actions. Maybe this works for me because i am not the sort who says 'i love you' a lot but i know for a fact that my kids and husband are in no doubt that i love them because of the relationship we have. It is not the words that matter - it is the actions. And when i look at Buffy and Spike in season seven I see love in action. I see forgiveness and concern and trust and belief and freindship and companionship and respect and....LOVE.
Buffy says the words, I believe her.
