I am looking for a story where Sess gets a new girlfriend and leaves his best friend Kagome alone completely. When he breaks up with her, he tried to go back to Kagome but she says she is no longer his friend. I know the story is incomplete but I just cannot remember the name. Any help would be appreciated.

Hi no this is not the one but a good one though. I this one he was dating Rin and he broke up with her and then tried to pick back up his friendship with Kagome but she called him by his last name "Mr. Taisho" and hung up on him and he had to work to get back in her good graces. Inuyasha is also a little toddler and calls her gom gom.

I think this story is:

Never Forget By BelovedStranger

Kagome vows to make Sesshomaru feel the same heartache he has inflicted upon her, but will her vengeful schemes backfire when, finally, Sesshomaru realizes how much Kagome means to him and vows to mend her broken heart?

I know what story your talking about but I can't remember the name. The author was Pensierri32 but she has taken down her stories on this website and FF.net.

Kagome and Sesshomaru were best friends but then Sesshomaru started dating Rin and started to ignore Kagome. They also worked in the same company. Once Rin's true colors started coming out he dumped her and started to rebuild his friendship with Kagome. While doing that he realized he had always liked her and started to pursue her.
