听力原文：W: Hi, Jack, it is a long time ever since we graduated. How have you been? M: Not very well, Maggie. W: Why? Looks like you're feeling very down! What happened? M: Nothing. W: Come on. For a man who's feeling so down, there're usually two reasons. Either his career is going downhill, or he has a broken heart. Since you're so successful, it must be the other. M: Well, you're right. I just broke up with Jane. W: Oh, I'm sorry. I thought you two were made for each other. M: Well, you never know. I'm ready for a commitment and want to settle down, but she says she wants to pursue her career while she's still young. W: Well, you can't blame her. It's always difficult to choose between career and family. M: Maybe you're right. W: Jack, I don't know what to say to comfort you, but cheer up! There's plenty of fish in the sea and you'll find your soul mate, your perfect match! M: Yeah, but it's hard to forget her at the moment. You know, we were together for almost five years. It's really hard... What is Jack's initial reaction to Maggie's concern?
