Several times he turned his head and looked back for their car, and if the traffic delayed them he slowed up until they came into sight. I think he was afraid they would dart down a side street and out of his life forever.
Tom regards Daisy as his possession which he is now in danger of losing. Tom is so angry about his wife’s affair is because it is not in his control. While he needs to have an affair to feel that rush of his college days, he knows that he still loves his wife and still wants to be with her. But he doesn’t know if Daisy loves Tom or Gatsby more, and he recently witnessed Myrtle essentially choose George over him. So he is now incredibly scared of Daisy doing the same and choosing Gatsby.
