Anyways would be great if there were another one out there where he leaves her...

nope thats not it, it was kinda angst, just dunno if she had twins or just one baby, she forgives him and they end in bed.... then willow asks her something like: did you use protection????? and she reach down the bed and trash to see if she did, she calls spike and he said he doest want to know about her .... xander is very angry , it was sooooooo long ago, but it wasnt finished when i lost internet so maybe she finished it or something, thank you lots for answering Vamp :))))
