Because Tsunade is afraid that she might lose Jiraiya too cos
he's going to a dangerous mission alone that he might die ,that we all know that that's going to happen when he fight Pein.
also cuz she loves Jiraiya <3 She's known him since she was a littl kid and she doesn't want to lose him, she loves him more like a brother than romantically though (although she does love him romantically somewhat but not as much as family-wise) :)
