Ok the group defeats naraku i think and one of kagomes friends falls through the well and gets stuck in the past and marries inuyasha. kagome mates sesshoumaru. Her friend is really jealous of kagome and raises her daughter to hate her. inuyashas other kids are a little messed in the head. a new evil sweeps across the land and sesshoumaru and kagome leave japan. they live in a cave and it goes in depth on her having children full blooded if i remember correctly. then they come back to japan and the evil has almost taken over everything. a godess from hell wants kagomes soul so she tricks inuyashas daughter into helping lure kagome out. they all go down into hell and defeat her. thats all i can remember.

i appreciate the help

That sounds awfully similar to Demonlordlover's A Sentinel Mother.

Summary: Marked by the gods, claimed by Sesshoumaru, Kagome gives up her dreams of a normal life to become mother to a special breed of youkai, the Sentinels.
