Spidey's saving himself for marriage.
If Carol is going to have a serious romantic relationship, it's not going to be with Spider-Man.
Personally, I love the idea of Spidey being used as a Boy-Toy by some Super Powered Sexy, But, As some have pointed out, Spidey does tend to wear his heart on his sleeve.
I am imagining Carol; Or my personal Spidey fantasy, Jennifer Walters; Attempting to gently explain to Peter that it was only a one night stand while Petey is busy daydreaming about getting married in Shea Stadium and having lots of little green Spider-Babies.
Ah, I bet Black Cat secretly has a wall full of Spidey's pictures on it again secretly. Do we know why they broke up originally now post OMD? Or should I not ask and slink away..? Sorry Marvel...
Well, Pete broke up with her originally cause Cat didn't like Peter Parker, just Spider-Man. From what you've said I'm assuming that they've just altered that slightly to be that Cat didn't want to know who he was.
I didn't really pay attention to the new Black Cat issues of ASM, it just wasn't the Felicia I was used to and interested in.
OMD didn't change any past continuity, except Peter and MJ were "in a committed relationship" instead of "married" and possibly weren't pregnant with baby May. Everything else happened as we knew it.
