Why Ranbir not giving Katrina a closure?

"Kat knew he was there and her car was seen a few times in that area. It really looks like she wants to talk to him and he has cut off all communication with her. I think he owes her a conversation. No one is asking them to get back together. But if she wants closure, he should give her that. He owes her that. It is the decent thing to do," a source said.
