Hmmm...Were you watching with subtitles? I saw the episode too, and I had no subtitles, but my understanding was that one of the women called him to start another affair with him. They both have children so it's like we don't know who it is that called him. He probably does still love them, that's why he looked back at the end. They were all supposed to walk away without looking back, and he was the only one who really did. I don't really understand what you mean with the last question. I would think if he felt guilty he wouldn't marry the other girl, because it would be disrespectful to his first wife.
