Ivan really wasn't expecting Arna to return to him. He felt his instincts were betraying him when it strongly said she was leaving him.
Having no idea what was going on in her head, he coaxed her for the period she was going through. He gently rubbed her back, "Snow, everything will be alright. You don't have to show yourself strong all the time. Speak with me, okay?..."
He cajoled her while she cried hearing him as she reflected on her thoughts and actions of two weeks. Everyone at home treated her the same as before to avoid making her feel guilty but if they behaved naturally or special, she wasn't able to overcome her guilt no matter what.
Even though everything felt normal with their actions, a part of her was thinking they might be doing it to cheer her up as she wasn't with her family for so many years. They used to share if there was any good news, but she had none, other than being happy for them.
