This is always bugged me...
What was the entire point of Sesshomaru marrying and impregnating Rin if he decides to barely spend time with his family? In the anime he give up his Lord title so he have to attend much less duties and mostly depends on Sesshmom's money. He doesn't have the same issue like a commuting parent or someone serving in the military. Yet he chooses being an absent father, only to interfere when it's danger.
In the manga shortly after Towa and co return from the modern era, he immediatly leaves for "buying clothing", and come back days later... only to send them off to China for "training". I've seen Srins hoping him travelling with Rin again for a third baby (mostly a son, as they need to copy the Mirsan family badly). But what are the odds he would treat his 3rd child differently than the wondertwins? Leaving the baby and Rin in the village again and avoiding contact, like he did with Inuyasha during his childhood? Merely using Rin as babyfactoring machine in Zeus-style?
The more I look into it, Se***in as whole feels like a dystopian marriage under the guise of "wholesome and cute" cover.
