No the show left an open ending. She didn't even know he was alive.

In the comics Bangel have pretty much been ruined.

Spike is with Buffy now and is there for her like always.

If Buffy really does have this baby. I think Spike will take the place as daddy.

It better not be his though.

The comics still aren't canon to me.

There are a lot of fans that do consider them though.
