WZEN-075 Banned 23 Full-time housewife Minami (29)

I've lived my life seriously for 29 years. During my student days, I never felt like rebelling, and I got married early at 23. I never strayed or made mistakes, everything was smooth...or so it seemed. But last week, my husband suddenly told me he wants a divorce. We were supposed to be happily married...right? I don't know the reason, and now I've been left behind, all alone. What should I do from here? Please, someone tell me.
