We probably have to assume she either reincarnated way after family members would have died then and thus, her search would be futile.
We could also assume that she went numb to most feelings after living through life too much. That is not to say that she did not hold affection for her for er family members, maybe she thought it was better to noy mix her lives up, otherwise, she would never move on.
Well, no matter the case, she is mixing different lives' affairs right now, which is probably something she didn't do in the past.
