Ok, I was ask to explain more about the story I am searching:

Kagome is cursed with immortality and she wanders everytime she has this feeling, until it stops. In those wanders, she is hurt and Sesshoumaru takes her to his castle until she heals, and offers for her to stay . By that time, Sesshoumaru has a son (I think his name is Taro, I am not sure, and this story I am telling is not: Choices and Consequences!), he has an underdeveloped digest system, so Kagome heals him.
In a card game with Sesshoumaru she gets pregnant, but she has this feeling of wandering, and she leaves the castle with Rin (who is already a woman, and has just lost his husband.)

When Sesshoumaru finds her, she is figthing with demons and Rin and her daughter are in a cave. Sess takes her back to the castle...

That's all I remember! I hope someone can give me hints!

Thanks!!!

Oh, that sounds so familiar! Now you have me wanting to read it too! I hope someone knows the title...

Its called Living Through Time. It seems like the story used to be longer....

I just read that, it is a nice story. They just updated it on the 4th of this month, maybe the author is revamping it.

Thank you sooo much!!!!
