My 21F fianc? has been crying over a male friend moving to a different city for over 8 days and that is making me(21M) feel jealous. Is her response normal and how do I approach talking with her about it?

So I am thinking about whether i should confront my fianc? about this and how should I go about doing it... I don't believe they were in a relationship but since 6 days she has been calling me and crying about him. She has been completely depressed. Now just over a male friend as it is lasting for so long, it is making me feel insecure.
I know when she is broken I shouldn't ask her. But I really want to ask if she had any feelings for him. Because this prolonged crying about a male friend just moving to a different city is giving with my brain. Like I can understand it for 3-4 days, but now it has been 8 days. She has stopped going to her job as a receptionist since 8 days also. I don't know how do I console her while feeling jealous myself. Please help with your opinion about this issue.
TLDR: My fianc? has been crying over her friend moving to a different city for over 8 days and I find that response excessive and it is making me feel jealous
