Cindy Moon is a girl who was bit by the same Spider as Peter, however she was kept in seclusion to hone her powers by Ezikiel for 6 Years and keep her away from Morlun. Peter freed her and told her that Morlun was dead, so she became Silk.

Of course, Morlun came back in the Spider Verse plot (his second resurrection) but that's not the interesting part. The Interesting thing is that Cindy has a Stronger Spider Sense to Peter and her webbing is insulative, her and Peter can't spend much time together though, because they both let off Pheromones that put them into a wild sexual frenzy (which is likely because they were made by the same Spider so genetically they're compatible and their Spider Senses are forcing the natural instinct to reproduce on them)

I think they do like each other but Cindy wants to be her own Person and Peter doesn't want to rely on pheromones, she is dating the Human Torch - to Peter's behest - last time I checked
